Hi Fabrizio,

I tried this some time ago with Ubuntu 9.04 as guest OS. I remember I
had to explicitly enable USB devices individually. I did that via
Devices->USB Devices in the main menubar after I plugged in the USRP
(I think you can also do that if you click on the small USB connector
icon at the bottom of the VM window).
It was running (http://twitpic.com/wyylv) but performance on my iMac
was very slow. I couldn't make 3D acceleration work and the VM
couldn't keep up with USRP data rates except with decimation rates >
250, so I abandoned that experiment.
