[Bug 1017072] Re: 046d:08c1 Regression: Quickcam Fusion doesn't work after first time


G'day Eric.

Do you know if the fix you mentioned made it into an Ubuntu release?  Is
this problem still occurring on Ubuntu 15.04 "Vivid Vervet"?

You received this bug notification because you are a member of Kernel

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

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

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.
