Re server crashes on Linux

Hello,

I am having a problem with the virtual here server on linxux (Lubuntu on a macbook pro) ...
I am virtualising a usb 2.0 camera device (Ophir Optronics, SPCAM SP620U 1/1.8" CCD 1600x1200). This camera is connected to a linux machine. After trying to start the software that uses the camera on the client machine, the server machine crashes... I have attached the server log below.

cheers,
Daniel
