Title:
  046d:08c1 Regression: Quickcam Fusion doesn't work after first time

Status in Linux:
  Fix Released
Status in linux package in Ubuntu:
  Fix Released

Bug description:
  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.

  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.

  046d:08c1 Logitech, Inc. QuickCam Fusion

  WORKAROUND: If I unplug the webcam and then plug it back in, then the
  video shows up again -- at least for one time.
