And kernel says

uvcvideo: Failed to query (135) UVC control 11 (unit 5) : -32 (exp. 1).

I made a patch that fixes this. I attached an updated version that should apply cleanly on top of the current svn version. I think Laurent is working on a better fix for the problem, but you can use this one until it is finished. Hope it helps.


Best regards,

Juho
