I wrote simple to use software that turns your Raspberry Pi into a USB server. Its pretty useful for remotely accessing USB->Serial converters, JSB programmers, accessing printers/scanners removely, and basically any USB device. Its like having a USB hub that you don't need to plugin. Take a look here http://www.virtualhere.com for more information if you are interested.

I wrote a USB over IP server for raspberry pi and I setup a small one person company to promote it. It can be found here http://www.virtualhere.com/usb_server_software
