Subject: webcam problem after suspend/hibernate
Hi,
After suspend/resume, I have my webcam no more working.
The /dev/video0 file still exist, but the webcam won't be used until I do this :
rmmod uvcvideo
modprobe uvcvideo
(2.6.31.8-0.1)
This is may be caused by a bug somewhere.
These are more information about my hardware :
I have Microdia webcam
