Can USB Devices Be Exported Over a Network?
While I know that it's possible to use something like SANE to share a USB scanner over a network, or use NBD or iSCSI to share a USB flash or external HD over the network, I've been wondering about a raw USB <--> TCP/IP transport. Back in the late 90s, I swear I remember hearing about a project for the Linux kernel to be able to export USB devices over a network using SCSI packets over TCP. Did this evolve into the iSCSI projects, or is there still something out there that would allow me to take something like a support USB graphics tablet and export the USB device to another host?

My application for this is the thin client model I'm using at home. I use NX for the thin client and FreeNX for the server side. While I can connect my graphics tablet and use it on the thin client with it's local X server, I am not able to have an application like Gimp on the application server recognize my tablet. I think this would only be possible if I could take the raw USB device and export it to the application server which would then map it to the server's /dev/input hierarchy.

However, the uses go farther than that. In general, I'm really just looking for a way to plug a USB device into my thin client (a laptop) and export it to the application server. This would help me out with a number of applications. Anything like that out there?

NAME

       usbredirserver - exporting an USB device for use from another (virtual) machine

SYNOPSIS

       usbredirserver [-p|--port <port>] [-v|--verbose <0-5>] <usbbus-usbaddr|vendorid:prodid>

DESCRIPTION

       usbredirserver  is a small standalone server for exporting an USB device for use from another (virtual) machine through the usbredir proto-
       col.

       You can specify the USB device to export either by USB id in the form of <vendorid>:<prodid>, or by USB bus number and  device  address	in
       the form of <usbbus>-<usbaddr>.

       Notice  that  an  instance of usbredirserver can only be used to export a single USB device. If you want to export multiple devices you can
       start multiple instances listening on different TCP ports.

OPTIONS

       -p, --port=PORT
	      Set the TCP port to listen on to PORT

       -v, --verbose=VERBOSE
	      Set usbredirserver's verbosity level to VERBOSE, this mostly affects USB redirection related messages. Valid values are 0-5:
	      0:Silent 1:Errors 2:Warnings 3:Info 4:Debug 5:Debug++
