Hi Laurent,

I did check the faq and when i type:

lsusb -d 06f8:3003 -v | grep "14 Video"

i obtain the following lines:

can't get device qualifier: Operation not permitted
can't get debug descriptor: Operation not permitted
cannot read device status, Operation not permitted (1)

So i think that my web cam is not UVC Compliant ?
If it is the case, do you have any idea about the kind of driver i 
should use ?

however, bellow the traces (i have usbutils release 0.73-8ubuntu3).

lsusb -d 06f8:3003 -v
