Hi Mark,

The /dev/video0 exists and the cheese application (used for testing) seams to 
find it. But the menu for choosing the camera is greyed as if it was unusable.

The message I get in /var/log/messages is:
     kernel: uvcvideo: Failed to query (GET_DEF) UVC control 6 on unit 2: -110 
(exp. 2).
each time I launch the cheese application.

Patrick
