This User Manual applies to the Keyspan USB Server Software Version 1.3.x. Patent Pending. Rev 2005jun23 Page 12
Tech Note: Using Multiple USB Servers and USB Devices: US4A/PS4A: You can view up to 8 USB Servers in the Keyspan Server Utility software. If you are using all of the USB ports on your 8 servers, you will be able view a total of 32 USB devices in the Keyspan Server Utility software however you will only be able to have 12 USB devices 'connected' to your computer. If you need to use a 13th USB device, 'disconnect' one of your 12 USB devices via the Keyspan Server Utility software to free a location for the next USB device. If you need to have more than 8 USB Servers, configure your next 8 servers to use a different UDP port. Once you have done this, use the USB Software's Local UDP Port menu item to switch between your first 8 servers and your next 8 servers. Tech Note: Using One USB Server With Multiple Users: Only 10 users can connect to a single or set of USB Servers using the same UDP port. You can support more users by setting up additional USB Servers with different UDP port numbers.
Other Methods To Connect Your USB Devices
Using the USB Server program to connect and disconnect your USB devices (as outlined above) is only one method of connecting devices. While the USB Server program gives detailed information about your USB Server and USB devices connected to it, you may not always want to open the USB Server program every time you want to use your USB device. Because of this, we have created other methods to connect your USB devices. With the USB Server 1.3 software, you can: Automatically connect and disconnect printers for improved printer sharing (by using the Auto-Connect feature) Connect and disconnect USB devices without opening the USB Server program (by using the USB Server system tray feature) Reclaim or Force Disconnect a device that has been left in use by another user. Not 'share' your USB devices and Automatically connect USB devices to only one computer (by using the Single-User Connect Mode) The following subsections show you how to use these different features.
Using The Auto-Connect Feature For Windows
This feature will automatically connect and disconnect printers whenever you have a print job queued. This gives you a richer printing experience that is similar to using a print servers. Note: This feature is only enabled in the Multi-User Connect Mode for USB devices that are using the Shared Share Mode.

Using Device Force Disconnect
The Force Disconnect command allows you to disconnect a USB device from another computer if that USB device that has been left 'in use' by another user. To Force Disconnect a device, select the
This User Manual applies to the Keyspan USB Server Software Version 1.3.x. Patent Pending. Rev 2005jun23 Page 18
Keyspan:USB Server - User Manual device in the USB Devices tab then select the Force Disconnect command from the Advanced menu. Follow the instructions on screen to complete the process. Please note that if your USB Server has an administrator password enabled, you will be asked to enter that password before you can Force Disconnect the selected USB device.
IMPORTANT NOTE!!! Force Disconnect will disconnect a USB device that is connected to another user's computer. This is the same as physically disconnecting the USB device's cable from the USB port. As with any USB device, it is not recommended to disconnect (or Force Disconnect) any USB printer while that device is in use (ie disconnecting a printer while it's printing). You should only use Force Disconnect if you are sure that the USB device is not in use. Please note that if your computers automatically 'sleep' (aka 'hibernate', 'power save', etc.), USB devices connected to the sleeping computer will be released and made available to other users. Turning off your computer will also release USB devices left in use.
Using The Single-User Connect Mode
The USB Server has two Connect Modes: Multi-User and Single-User. By default, the server is set to use the Multi-User mode. In Multi-User mode, USB devices are shared in a one-user-at-a-time mode. This allows multiple computers to use one USB device. Again, you need to 'connect' to the USB device before you can use it (thus preventing other users from using your USB device at the same time). Single-User mode will automatically connect USB devices to your computer without you having to connect or disconnect. When your USB Server is set to Single-User mode, it will 'connect' all of the USB devices connected to the server to the first computer (with Keyspan Server Utility software) it detects. Use this mode, if A) you only have one computer or B) you have multiple computers but only one computer will have access to the USB Server. Connect Mode (Multi-User or Single-User) can be configured in the USB Server's Servers tab. For details, please see the Changing USB Server's Settings section later in this manual. The Single-User Connect Mode affects an entire USB Server. Please note that you can also configure a single USB device to be dedicated to particular computer and still share other USB devices with other computers. For details, please see the XXXX section later in this manual.
USB Device Status Details
The Keyspan USB Server's USB Devices tab will show the 'connection' Status of USB devices connected to the server. The following is a list of the possible states of USB devices connected to the USB Server.

In this window, enter the serial number of the USB Server (the last five digits of the Network Address printed on the bottom of your USB Server) and the IP settings that you want to send to the USB Server

After the boot up, the status lights will have new meanings. Now that the server is running, we will use the status lights to troubleshoot the USB Server.
This User Manual applies to the Keyspan USB Server Software Version 1.3.x. Patent Pending. Rev 2005jun23 Page 49
SYSTEM Status Light: 1 Look at the SYSTEM status light 1 (the green leftmost light under SYSTEM). If the light is:
Off: Check the USB Server's power supply and its connection to an outlet. If you have done this and the light does not turn on, please contact Keyspan technical support. On: If this light doesn't blink on/off within 6 seconds, the USB Server has failed to boot up. Please try Resetting Your USB Server Hardware (as described later in this section). If it still fails, contact Keyspan technical support. Blinking Slowly: This is normal and indicates the USB Server hardware is working. Proceed to the next light. Alternating On/Off With System Lights 2 and 3: If the System 1 (green) alternates on/off with either System 2 or 3 (red), so that when System 1 turns off, System 2/3 turns on and vice versa, the USB Server has encountered an error while loading its firmware. Contact Keyspan tech support for assistance.
USB Status Lights: 1-4 Look at the USB status light (any green light under USB). Next locate the light that corresponds to the USB port that your USB device is connected to. If the light is:
Off: Check the USB Server's power supply and its connection to an outlet. If you have done this and the does not turn on, please contact Keyspan technical support. Blinking: This indicates the a) USB Server hardware does not support your USB device b) if you or is having problems communicating with the device. Please check the the USB Server's USB Device Compatibility information (found in the Appendices) or contact Keyspan for further support. The USB lights will also blink if you have exceeded the number of USB devices per server. The USB Server support up to 8 USB devices on one USB Server. While many USB devices appear as one USB device, components of Compound USB devices (a device with an embedded hub or a device that has multiple components tied together by an internal USB hub) will count as one device each. For example, the Lexmark X1150 is a compound device that has 2 components (one for the scanner, one for the printer). The Canon i475D is also a compound device that has 3 components (the printer, the card reader, and a HID device [for buttons on the printer]). If you connect four X1150 devices you are still under the 8 device limit and the USB lights will not blink. If you have 3 Canon i475D, you have 9 USB devices and are over the limit therefore the light will blink.

If you still cannot see your server, proceed to the Troubleshooting:Network Issues sub section. Is Listed: This is normal and indicates the USB Server hardware is working. Skip ahead to the Troubleshooting: USB Devices sub section.
Troubleshooting:Network Issues
At this point, your Keyspan Server Utility software is communicating with a specific network. Unfortunately, the network link between your computer and your USB Server is broken. The following are suggestions on how to solve these network related issues.
Firewalls A 'Firewall' is a piece of software or hardware that helps keep your network safe by preventing hackers from getting inside your network and also by preventing you from sending private data to outside networks (ie the Internet).
Firewalls are either hardware (a physical item on your network ie your DSL router) or software (resides on your computer ie Windows XP's built-in firewall software). In most cases, these firewalls are configured to only allow 'basic' internet traffic (web, email, ftp, etc.) to come in and out of your network. Since the USB Server is a new product, these firewalls usually do not know ABOUT KEYSPAN SERVER SOFTWARE network data and may prevent you from communicating with your USB Server. If you are using a firewall, configure the firewall software to allow UDP traffic on port 3842 as well as allow TCP/IP traffic on port 3842. The USB Server uses both UDP and TCP/IP to communicate. If you have configured your firewall to allow UDP and TCP on port 3842 and you: Cannot See Your Server: skip ahead to the Wireless LANs or Wired LANs sub section. Can See Your Server: Your firewall was preventing access to the Keyspan USB Server. If you had to configure a software firewall on your computer, please note that you have allowed only your computer to see your USB Server. If you configured a hardware firewall, test other computers to make sure that they can the your USB Server.
Tech Note: We have included step-by-step instructions on how to configure the software firewall that is built into Windows XP. You can find these instructions in the Windows XP Firewall Configuration appendix in this manual.
Wireless LANs If you have a wireless network, please make sure that your wireless base station has Ethernet Bridging enabled. Ethernet bridging allow wireless computers to act as if they are directly connected to a wired network. If this feature is not turned on, your wireless computers will not be able to see that Keyspan USB Server where as your wired computers will have full access.
To test this, temporarily connect your wireless computer to your network via a wired connection (ie

This User Manual applies to the Keyspan USB Server Software Version 1.3.x. Patent Pending. Rev 2005jun23 Page 52
Keyspan:USB Server - User Manual connect using an Ethernet cable). If you are not able see the USB Server after you've connected your computer via a wired connection, please skip ahead to the wired LANs spend USB Server sub section. If you are able to see the USB Server when wired directly to the network, then you do not have Ethernet Bridging turned on. Please enable Ethernet bridging on your wireless base station (refer to your wireless base station's documentation for further instructions). If you have done this and are still not able to see the USB Server, please contact Keyspan technical support.
Tech Note: In most cases, wireless base stations and routers have Ethernet bridging enabled. Older base stations and router may not have Ethernet Bridging enabled or may not even support it. Please check your wireless base station's documentation for details.

Wired LANs

If your computer and your Keyspan USB Server are both wired to your network via a physical cable and you are not able to see the Keyspan USB Server, you may have issues with your network hardware (ie your ethernet hub, ethernet switch, or router). To test this, connect the Keyspan USB Server directly to your computer via an ethernet cable. At this point, check the Keyspan Server Utility application can see if your server appears. If it does not show up, disconnect the USB Server's power supply for 10 seconds then plug back in. Wait 10 seconds for the USB Server to boot up then see if the USB Server appears in the Keyspan software. If your server does not show up, contact Keyspan technical support for further assistance. If your server does show up, try moving your USB Server and computer to the same ethernet hub/switch. If this does not solve your problem, contact Keyspan technical support for further assistance.
Tech Note: Some Ethernet hubs/switches may not properly route UDP and TCP traffic when connected to other hubs and switches. This is especially true when your USB Server is using Zeroconfig to obtain an IP address. To avoid these issues, connect your USB Server and your computer to the same Ethernet hub/switch.
WANs If you're trying to access your USB Server across a WAN (ie you want to access your USB Server at home when you are at work), you'll need to create an entry in the Server Access Settings in the LOCAL SETTINGS tab. This tells your Keyspan Server Utility to connect to remote server.

USB Device Compatibility

The Keyspan USB Server hardware (model US-4A) supports USB devices, USB multi-function printers, scanners, hard drives, HID devices, and other USB devices. The USB Server supports up to 8 USB devices on one USB Server. While the USB Server only has 4 USB ports, we support 8 devices due to how Compound USB devices work. Compound USB devices are devices that have multiple components connected to an embedded USB hub inside 1 USB device. For example, the Lexmark X1150 is a compound device that has 2 components (one for the scanner, one for the printer). The Canon i475D is also a compound device that has 3 components (the printer, the card reader, and a HID device [for buttons on the printer]).
Tech Note About USB Devices: Technically speaking, USB devices can either be a single USB device (a USB printer that contains only one component ie a single button mouse), a composite USB device (a device that contains multiple components but appears as one device ie a multifunction printer), or a compound USB device (a device that has multiple components that are tied together by an embedded USB hub inside the USB device itself ie a printer with a card reader, a keyboard with a port to connect a mouse, etc.). Using single and composite USB devices via the USB Server is identical to using them when connecting to built-in port. By default, compound USB devices also work the same way as when they are connected to a built-in port however you can OPTIONALLY configure the USB Server to allow you to connect to certain components of a compound device instead of connecting every component. This is useful if you just want to connect the printer component of a multi-function so that you don't get any message screens regarding the scan component of that device.
The USB Server, part# US-4A, supports ANY USB device provided the USB device:

TROUBLESHOOTING: If you do not see your USB device in the Keyspan USB Server application, please proceed to the Troubleshooting:USB Devices section in this manual.
Step 2 - (Virtually) Connecting Your USB Device
In the Keyspan USB Server application, the Other Devices area shows USB devices that are connected to the USB Server but require further action in order for you to use them. To use your USB device, you must first "connect" to it. To do this, click on your USB device under Other Devices and then click the CONNECT button as shown below:
This User Manual applies to the Keyspan USB Server Software Version 1.0 Rev 2004apr06 Page 8
Keyspan:USB Server - User Manual After you 'connect', your USB device will move under the My Devices heading. At this point, you can now use this USB device (or any other USB device located under the My Devices heading) as if it is connected to directly to your computer. MULTIPLE USERS NOTE: When you are connected to 'My Device', other users will notice that the USB device has remained under Other Devices and will now have a status of 'In Use' as well as show the name of the computer that is using that USB device. Other users will not be able to use any USB device that you have 'In Use' until you disconnect from it. When you are finished using your USB device, select your USB device under My Devices and click the DISCONNECT button. For you, the USB device will return to Other Devices. Other users will notice that the device has become available again.
Tech Note: By default, the USB Server is configured to use the Multi-User sharing mode. In this mode, all USB devices will be shared in a one-at-a-time mode. Before you can use a USB device, you will have to connect to it to gain exclusive access. Once you are finished using the USB device, you will have to disconnect from that device before others can use it. You can configure the USB Server to use other sharing modes, such as Single-User mode. For more details, please read the Sharing Modes Overview sub-section at the end of this section.

TROUBLESHOOTING: If a device in use by another user, you will notice that device under Other Devices showing up as In Use. It will also show that user's computer name. If you wish to use a USB device that is In Use, you'll have to wait until that user finishes using using it. Now that your USB device is located under My Devices, you can start using your USB device as if it was directly connected to your computer.
Step 3 - (Virtually) Disconnecting Your USB Device(s)
When you are done using your USB device, you must virtually disconnect it from your computer before it is available to everyone else on the network. To do this, open the Keyspan USB Server application, select your USB device from the My Devices area and then click the DISCONNECT button (see next image):
This User Manual applies to the Keyspan USB Server Software Version 1.0 Rev 2004apr06 Page 9
You'll notice that the USB device will move down into the Other Devices section. For other users, they will notice the USB device's status changes to Available.
Tech Note: Some USB devices may require additional action PRIOR to 'disconnecting' your USB device. For example, some USB devices will require you to drag the device's icon to the trash, stop the USB device's software, etc. If your USB devices requires such actions when the device is directly connected to the computer, please do these actions prior to clicking the DISCONNECT button in the Keyspan USB Server software.
Step 4 - Finishing Up and Additional Notes
You have now learned to use your USB device via the Keyspan USB Server. If you need to connect additional USB devices, note that you can connect up to four supported USB devices to one Keyspan USB Server. If you need to connect more than four USB devices you will need to another USB Server. USB hubs are not supported on the USB Server.
Tech Note: Using Multiple USB Servers and USB Devices: You can view up to 8 USB Servers in the Keyspan USB Server software. If you are using all of the USB ports on your 8 servers, you will be able view a total of 32 USB devices in the Keyspan USB Server software however you will only be able to have 12 USB devices 'connected' to your computer. If you need to use a 13th USB device, 'disconnect' one of your 12 USB device via the This User Manual applies to the Keyspan USB Server Software Version 1.0 Rev 2004apr06 Page 10

Keyspan:USB Server - User Manual Network Settings: Configure The Configure pop-up allows you to change how the USB Server obtains it's network settings (ie IP address, Subnet Mask, etc). Using Default (default setting): In this mode, the USB Server will try to get an IP address via DHCP first. If it fails to obtain an IP address within 10 seconds, it will assign itself an IP address via Zeroconfig. This is the recommended setting for most users. Using DHCP: In this mode, the USB Server will automatically obtain an address via DHCP server. Use this setting if you only want to use an IP address obtain via a DHCP server (ie a DSL router, etc.). Using Zeroconfig: In this mode, the USB Server will assign itself an IP address via the Zeroconfig protocol. Use this setting if you are in a network where you only want to use Zeroconfig IP addresses. For more information about Zeroconfig
Tech Note:Zeroconfig: Zeroconfig (aka Zeroconf) is networking protocol that allows computers to automatically find each other without the need for you to enter IP addresses, configure DNS servers, or setup DHCP. You can get more information about ZeroConf at http://www.zeroconf.org/ and http://developer.apple.com/macosx/rendezvous/
Manually: In this mode, you will manually enter your IP Address, Subnet Mask, and Gateway Address. Use this mode if Network Settings: IP Address/Subnet Mask/ Gateway The USB Server will show it's current network configuration in the IP Address, Subnet Mask, and Gateway fields. You can only enter data in these fields if you have the Configure pop-
This User Manual applies to the Keyspan USB Server Software Version 1.0 Rev 2004apr06 Page 15
Keyspan:USB Server - User Manual Network Settings: UDP Port/TCP Port The UDP port and TCP Port fields allow you to specify which port numbers the USB Server will communicate on. This communication happens between the USB Server hardware and software. By default, these ports are set to 3842. Port 3842 is reserved for exclusively for the Keyspan USB Server. Other IP services (ie ftp, email, web, etc) cannot use this reserved port. UDP Port (default is 3842): Change this setting to change the UDP port number that the USB Server will broadcast itself on. Other computers configured to use this UDP port number will be able to see this USB Server. This setting is useful if you wish to limit the number of people connecting to a particular USB Server or if you want to hide a USB Server from other users on your network.

IMPORTANT NOTE: If you change your server's UDP Port number in the Admin tab, you will also need to tell the Keyspan USB Server software to 'listen' to the new port. To do this, select the Local UDP Port command in the Keyspan USB Server application's Config menu (for details, see the Config Menu sub-section later in this section). You only need to change the Local UDP Port if you've changed the USB Server's UDP port.
TCP Port (default is 3842): Change this port to change the TCP port that the USB Server uses to transmit USB data.
Tech Note:UDP/TCP Ports and Firewalls: For most users, there is no need to change the USB Server's UDP and TCP ports however certain firewalls may block traffic to the default UDP and TCP ports. In these instances, you can either change the port numbers or configure your firewall to allow connections via USB Server's configured UDP and TCP ports.
Applying/Canceling Server Settings
Once you have changed the server's settings, you will need to apply your changes in order for the changes to take effect. To do this, click the Apply Changes button (see next image). MACINTOSH: This button is shown as Apply in the Mac software.
This User Manual applies to the Keyspan USB Server Software Version 1.0 Rev 2004apr06 Page 16
Once you Apply Changes, the USB Server (hardware) will disconnect any users connected to it and restart itself. Please note that your USB Server will disappear temporarily from the Keyspan USB Server application while it is restarting. If you do not want to keep the changes that you made, cancel your changes by clicking the Cancel button. Your USB Server hardware will not be restarted.
Restoring Default Settings
You can reset USB Server to factory settings by using the Keyspan USB Server application. To do this, select and edit your USB Server (as detailed earlier in this section) and then click the Restore Defaults button (see next image).
Restoring the default settings will cause the USB Server (hardware) to restart.
Tech Note: Restoring to default settings will also set the USB Server's UDP port to 3842. If you previously changed your UDP port, remember to change the Keyspan USB Server application's Local UDP Port to 3842. You may not be able to see your USB server if you fail to change your Local UDP Port. To change the Local UDP Port, select Local UDP Port in the Keyspan USB Server application's Config menu. IMPORTANT NOTE FOR FIREWALL USERS: If you've configured your firewall to allow access to the USB Server, remember to check your firewall's setting. The USB Server's IP address may have changed after restoring to default settings.

After the boot up, the status lights will have new meanings. Now that the server is running, we will use the status lights to troubleshoot the USB Server.
This User Manual applies to the Keyspan USB Server Software Version 1.0 Rev 2004apr06 Page 22
Keyspan:USB Server - User Manual SYSTEM Status Light: 1 Look at the SYSTEM status light 1 (the green leftmost light under SYSTEM). If the light is: Off: Check the USB Server's power supply and its connection to an outlet. If you have done this and the light does not turn on, please contact Keyspan technical support.

This User Manual applies to the Keyspan USB Server Software Version 1.0 Rev 2004apr06 Page 23
Keyspan:USB Server - User Manual users connected to the USB Server. If your computer is turned on, proceed to the Troubleshooting:UDP Ports sub-section. System 2 is Off / System 3 is On: The server obtained an IP address via Zeroconfig (ie you don't have a DSL router and you have not specified IP settings) and does not show any users connected to the USB Server. If your computer is turned on, proceed to the Troubleshooting:UDP Ports sub-section. Status 2 is Off / Status 3 is Off: This is normal and indicates the USB Server hardware is working. More specifically, the USB Server has obtained a IP address and has detected users (client computers) to it. Skip ahead to the Troubleshooting: USB Devices subsection.
Troubleshooting:UDP Ports
Make sure that your USB Server software and hardware are communicating on the same UDP port. To verify this, open the Keyspan USB Server application. You USB Server should appear (see next image):
In the Keyspan USB Server application, is your USB Server listed? If your server: Is Not Listed: The USB Server software cannot find the USB Server hardware. Change the USB Server software's Local UDP Port (use the Config menu and select Local UDP Port) to match the UDP port that is being used by the USB Server hardware. If you do not know the UDP port that your server software is using, try setting the Local UDP Port to 3842. If this still does not work, try Resetting Your USB Server Hardware (as described later in this section). If you still cannot see your server, proceed to the Troubleshooting:Network Issues sub-section. Is Listed: This is normal and indicates the USB Server hardware is working. Skip ahead to the Troubleshooting: USB Devices sub-section.
Troubleshooting:Network Issues
At this point, your USB Server software is communicating with a specific network. Unfortunately, the network link between your computer and your USB Server is broken. The following are suggestions on how to solve these network related issues. Firewalls A 'Firewall' is a piece of software or hardware that helps keep your network safe by preventing hackers from getting inside your network and also by preventing you from sending private data to outside networks (ie the Internet).

This User Manual applies to the Keyspan USB Server Software Version 1.0 Rev 2004apr06 Page 24
Keyspan:USB Server - User Manual Firewalls are either hardware (a physical item on your network ie your DSL router) or software (resides on your computer ie Windows XP's built-in firewall software). In most cases, these firewalls are configured to only allow 'basic' internet traffic (web, email, ftp, etc) to come in and out of your network. Since the USB Server is a new product, these firewalls usually do not know about Keyspan USB Server network data and may prevent you from communicating with your USB Server. If you are using a firewall, configure the firewall software to allow UDP traffic on port 3842 as well as allow TCP/IP traffic on port 3842. The USB Server uses both UDP and TCP/IP to communicate. If you have configured your firewall to allow UDP and TCP on port 3842 and you: Cannot See Your Server: skip ahead to the Wireless LANs or Wired LANs sub-section. Can See Your Server: Your firewall was preventing access to the Keyspan USB Server. If you had to configure a software firewall on your computer, please note that you have allowed only your computer to see your USB Server. If you configured a hardware firewall, test other computers to make sure that they can the your USB Server.
Tech Note: We have included step-by-step instructions on how to configure the software firewall that is built into Windows XP. You can find these instructions in the Windows XP Firewall Configuration appendix in this manual.
Wireless LANs If you have a wireless network, please make sure that your wireless base station has Ethernet Bridging enabled. Ethernet bridging allow wireless computers to act as if they are directly connected to a wired network. If this feature is not turned on, your wireless computers will not be able to see that Keyspan USB Server where as your wired computers will have full access. To test this, temporarily connect your wireless computer to your network via a wired connection (ie connect using an Ethernet cable). If you are not able see the USB Server after you've connected your computer via a wired connection, please skip ahead to the wired LANs spend USB server sub-section. If you are able to see the USB server when wired directly to the network, then you do not have Ethernet Bridging turned on. Please enable Ethernet bridging on your wireless base station (refer to your wireless base station's documentation for further instructions). If you have done this and are still not able to see the USB server, please contact Keyspan technical support.

Using your paper clip, quickly press the reset button inside the hole. This will reset/reboot your server. Reboot Server Into 'Safe Mode' Using The Reset Button If you've made an unwanted change to the USB Server settings and can't access your server anymore, you can boot your server into a 'safe mode'. In this mode, your server will reboot using default settings (ie Multi-user connect mode, default IP mode) and allow you to view and edit your server's settings. If you want to return to your settings, just power cycle your server. To boot into 'safe mode', press and hold the reset button until the lights turn off (this will take 3+ seconds). The USB Server is now resetting itself. It will take approximately 15 seconds to complete the reset. In the Keyspan USB Server application, make sure that your Local UDP Port is set to 3842. Once you've verified the port, check the the Keyspan USB Server application to see if your server appears. If it does not appear, please contact Keyspan technical support for further assistance.

When the USB server is first powered on, the (red) SYSTEM 3 light is ON while the server is booting. TROUBLESHOOTING: If this light never goes off or the 4 (green) USB lights never come on, you may have a serious hardware failure. Please contact Keyspan tech support immediately.
The (green) USB 1-4 lights are turned ON as the firmware starts running. SYSTEM 2 and SYSTEM 3 (both red) start flashing while the server looks for an Ethernet signal (aka a physical Ethernet connection). SYSTEM 2 and 3 will flash forever until the server finds this signal. SYSTEM 2 and SYSTEM 3 (both red) flash while the server tries to obtain an IP address. Once the server obtains its IP address, the server is completed booted up and running. The status lights will now have a new meaning. Please refer to the USB SERVER Is Running (Has Finished Booting Up) table. Tech Note: If the server is configured to use a Static IP address, the second stage is completed immediately. For DHCP only, it waits for the DHCP server. For Zeroconfig only, it takes about 1-2 seconds while it negotiates. For Default, it waits for DHCP for 10 seconds before taking a Zeroconfig address (1-2 seconds).
Now that your USB Server is running, please refer to the following table for detailed description of the server's status lights:

Windows XP Firewall Configuration
The following instructions detail how to configure Window XP's built-in firewall for use with the Keyspan USB Server. While these instructions are specific for this software, the basic idea of these instructions can be applied to configuring other firewalls. These instructions will show you how to: determine the Keyspan USB Server's port numbers and IP address access your firewall software add settings to your firewall to allow communication with your Keyspan USB Server
Step 1 - Determine Your Keyspan USB Server's Port Numbers and IP Address
You will need to know your USB Server's UDP/TCP port numbers and IP address prior to configuring your firewall. If you already know this information, skip ahead to Step 2. Otherwise, please read on. UDP and TCP Port Numbers The Keyspan USB Server defaults to using UDP port 3842 and TCP/IP port 3842. If haven't changed these settings, we will use these port numbers when we configure your firewall. If you've changed the USB Server's UDP and/or TCP port numbers, please note that you will have to enter your UDP port number instead of 3842. Obtaining Your IP Address To obtain your IP address, open the Keyspan USB Server application. When it is open, click the Admin tab and locate your USB Server. Click on your server and you should see its IP number under network settings (see next image):
This User Manual applies to the Keyspan USB Server Software Version 1.0 Rev 2004apr06 Page 39
IMPORTANT NOTE: If the Configure pop-up menu is set to Default, DHCP, or Zeroconfig, please note that your IP address is obtaining an IP address dynamically. Dynamic addresses can change at any moment making it harder for firewalls to keep track of. If you have need to use a firewall, we suggest that you configure your server to use a Static IP address.
Now that you have your IP address, proceed to Step 2.
Step 2 - Access Your Firewall Software
First locate your network connection's icon. To do this, go to the START menu, then to SETTINGS, then to Network. You should see an icon for your network connection (it is usually called Local Area Connection). When you see your network connection icon, right-click it to bring up the sub-menu (see next image):
In the sub-menu, select Properties. This will open the [Local Area Connection] Properties window. Click on the Advanced tab and then click the Settings button (see next image):
This will open the Advanced Settings window.
