Step 2 - (Virtually) Connecting Your USB Device
In the USB Devices tab, the following information is shown: Action: The Action column contains an icon Device Name: The name of your USB device. This is the name programmed into the USB device itself. Note: This name can be changed. Read the USB DEVICE CONFIGURATION subsection in the Changing USB Server's Settings section in this manual for more details. Status: This is the current Status of your USB device. This field is dynamic and will change as you start to use USB devices through the USB Server. For now, we're only concerned with the Available status (which means that the USB device is ready to used via the USB Server) but there are other Status. For details, please see the USB Device Status Details subsection later in this manual. Location: This column shows the server and server's USB port number that your USB device is connected to. For example, the location 'MyServer:3' means that your USB device is connected to USB port number 3 on the USB Server called 'MyServer'. Note: You can change the name of your USB Server. Read the USB Server Settings Descriptions subsection in the Changing USB Server's Settings section in this manual for more details. To use a USB device, you will need to first 'connect' your USB device via the Keyspan Server Utility software. To connect your USB device to your computer via the USB Server, select your USB device and then click the green Connect button under the ACTION column as shown below:

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.

The following is a description of all of the different settings you can change in the Network tab.
This User Manual applies to the Keyspan USB Server Software Version 1.3.x. Patent Pending. Rev 2005jun23 Page 28
Network tab: IP Address Assignment The IP Address Assignment pop-up allows you to change how the USB Server obtains its 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 obtained 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.
Tech Note:Zeroconfig: Zeroconfig (aka Zeroconf) is a 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/ Please note that computers using Zeroconfig can only communicate with each other when they are on the same Ethernet segment (ie all Zeroconfig computers are connected to same Ethernet hub).

This User Manual applies to the Keyspan USB Server Software Version 1.3.x. Patent Pending. Rev 2005jun23 Page 47
Tech Note: For a detailed description of every light and their status, please read the Status Light Behavior appendix.
SYSTEM Status Light: 1 While the USB Server is booting up, you will notice different lights turn on and off. The following table explains what these lights mean during the boot up process.
This User Manual applies to the Keyspan USB Server Software Version 1.3.x. Patent Pending. Rev 2005jun23 Page 48

USB Server Is Booting Up

STAGE 1 Server Is Booting Up

Status

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. TROUBLESHOOTING: System 1 and 2 Alternate Blinking: If System 1 (green) and System 2 (red) both blink alternately, the USB Server firmware has failed to update or load. Please contact Keyspan tech support immediately.

STAGE 2 Firmware Loading

The (green) USB 1-4 lights are turned ON as the firmware starts running. TROUBLESHOOTING: System 1 and 2 Blinking: If System 2 and 3 never stop flashing, the USB Server is not finding a valid ethernet connection or you've configured the server to use an invalid IP address. Please contact Keyspan for further details.
STAGE 3 Checking Ethernet Connection STAGE 4 Finding IP Address
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 Stage 4 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). TROUBLESHOOTING: System 2 and 3 Don't stop blinking: If System 2 and 3 never stop flashing, the USB Server is not finding a valid ethernet connection or you've configured the server to use an invalid IP address. Please contact Keyspan for further details.

Tech Note: While most USB devices will work with the USB Server, certain incompatible USB devices can be supported via future software updates from Keyspan. Please check the USB Device Compatibility appendix or contact Keyspan for more information about compatible devices.

SYSTEM Status Lights: 2 and 3 Look at the USB status lights 2 and 3 (the two red lights under under SYSTEM. Status 2 is the red light in the middle and Status 3 is the rightmost red light). Please note the status of Status 2 and 3. If:
System 2 is On / System 3 is On: The server has obtained an IP address via DHCP (ie your DSL router) 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. System 2 is On / System 3 is Off: The server is configured to use a Static IP (ie you've configured the USB Server's settings prior to troubleshooting) 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. 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) connected to it. Skip ahead to the Troubleshooting: USB Devices sub section.
Troubleshooting:UDP Ports
Make sure that your Keyspan Server Utility software and hardware are communicating on the same UDP port. To verify this, open the Keyspan Server Utility application. You USB Server should appear (see next image):
In the Keyspan Server Utility application's Servers tab, is your USB Server listed? If your server: Is Not Listed: The Keyspan Server Utility software cannot find the USB Server hardware. Change the Keyspan Server Utility software's Local UDP Port (use the LOCAL SETTINGS tab's UDP Port field) 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
This User Manual applies to the Keyspan USB Server Software Version 1.3.x. Patent Pending. Rev 2005jun23 Page 51
Keyspan:USB Server - User Manual 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 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 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.

Introduction Q&A

Keyspan USB Server
Connections for your Computer 222 0131
Q: Lets start with the obvious question. I know about a USB Card and a USB Hub, but have not heard of a USB Server. What is a USB Server? A: Our USB Server is a new concept. It is a way of connecting to USB devices over a LAN. Just plug the USB Server into your Ethernet network and then plug USB devices into the USB Server. This makes the USB Devices available to PCs and Macs on the network. Q: How does a USB Server work? A: The USB Server includes an embedded USB host controller. When used with software drivers that we have written, the USB Server appears as an additional USB host controller on each client PC. This allows the client PC to access USB devices attached to the Server. Part # MSRP: US-4A $129 Q: Do I need to install anything on the client PC? A: Yes. Keyspan USB Server client software must be installed on each PC or Mac. Q: Can I use a USB Server with any USB device? A: No. We support most USB devices -- including printers, scanners, storage devices, PDAs, digtial cameras and more -- but we do not support all USB devices. For example, we do not currently support USB audio products (i.e speakers) or USB video products (i.e. web cams). Our web site provides a compatibility list that is the best source of information on this topic. Q: Can all PCs on the network access a USB device that is connected to the Server? A: Yes, the USB device may be used by any client PC -- on a one at a time basis. If you do not want to make the USB Server accessible to all client PCs, you may configure the USB Server in order to limit access. Q: A USB Server sounds a lot like a print server. A: In general, thats true. A USB Server is similar to a print server in that it allows USB printers to be accessed and shared over a network. However a USB Server supports devices such as a multi-function printer or a scanner -- devices that a print server can not handle. These other USB devices are accessed by client PCs on a one user at a time basis. This is conceptually different than a print server. Q: So who are the people that are likely to benefit from using a USB Server? A: Small work groups. To us that means a home office, a small business or a classroom. These are all environments where you might have a small number of PCs on a LAN and a desire to share a USB peripheral such as a printer, a multi-function printer or a scanner. Q: All of the environments that you mentioned are rapidly adopting wireless networks. How does the USB Server fit into the Wi-Fi trend? A: If fits very well. Someone using a Wi-Fi based laptop does not want to have to physically plug a USB cable into their laptop each time that they want to print. Once a USB Server is installed on the wired part of the network -- perhaps near the Wi-Fi base station -- then it is easy to print to a USB printer via Wi-Fi. Q: Whats next? A: Look for us to release a Hi-Speed USB 2.0 version of the USB Server in late 2006 or early 2007. Though this will have minimal impact on use of printers and scanners, support for Hi-Speed USB will make it more practical to use storage devices on a USB Server.
