Comment 97 for bug 120434

Thanks for the commit, Alex! The latest code has just been added to the PPA. However, the packages have had this patch applied since February, so the problem is probably somewhere else. Moreover, the output that GeorgeV posted suggests that the firmware actually is in the camera whilst it's not working. Perhaps the cause might be the uvcvideo kernel module being unloaded.

GeorgeV, does running “sudo modprobe uvcvideo” fix the issue for you?
