http://usbip.sourceforge.net/ is an open source project on sourceforge for this exact thing. I haven't actually used it, but it's been slowly developed over the past couple years.
I haven't really followed this thread closely, but this seems like an excuse to suggest this ...
http://www.linuxdevices.com/news/NS9634061300.htmlWe should be able to build gnuradio for this using Angstrom/OE. The processor (although clocked at a ridiculous speed) won't be very useful for for doing gnuradio radio signal processing, but I suspect you could use the gr-udp blocks to send data over the network to a more capable machine for the actual processing.

PatrickFrom the web site the transfer rate of these boxes is 10/100Mb/s. So theoretically it should transfer a maximum of 12.5MByte/sec which is far below the required 32Mbyte/sec of USRP1.2 Points: 1) USRP is known to be able to transfer maximum 32 MByte/sec, but you do not need to run at this data rate. 2) USB/IP is not limited to this boxes. You can forward USB connections from a Linux box to any other Linux box. The mentioned boxes just happen to do this as their main task. You could do USB over IP forwarding via Gigabit Ethernet, that would give you about 100MByte raw transfer rate, which should be sufficient for maximum USRP data rates. Just wanted to know if anyone used something like this already. I could get hold of one Raidsonic part, maybe I'll give it a try. I'm not shure if USB/IP supports the transfer modes that the USRP uses.
