Public bug reported:
The first time I plug in this webcam, it seems to work ok (e.g., in
guvcview). If I turn off the webcam and then turn it on again, all I see
is a noisy screen with lots of multicolored horizontal lines (see
attached; colors change in response to waving my hand in front of webcam
lens, so I know it's still receiving/processing video from camera).
Sometimes, it works the second time, but after a few more times, I see
the video with just noise again. If I unplug the webcam and then plug it
back in, then the video shows up again -- at least for one time.
I see this problem after upgrading from Maverick straight to Precise.
This is reminiscent of bug 865131, which expired on 2012-05-30. I've
tested with mainline kernel 3.4 as well, with similar results.
