["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Patrick Welche, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  can't read uvcvideo (usb video / webcams) devices

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Attempting to read /dev/video0 for USB video device gives:

  libv4l2: error turning on stream: No space left on device

  from the video4linux library, and the video4linux ioctl fail with e.g.

  VIDIOC_STREAMON - Unable to start capture: Device or resource busy

  I wrote a test program and find that "Control" ioctls such as
  VIDIOC_G_FMT are successful: I can query the format which the camera
  provides, so the "connection" with the camera seems OK.

  Reading the frame, however seems impossible.

  (cheese and guvcview are also unable to display an image, so it isn't
  just my programming - and my program does work on a laptop which runs
  NetBSD, so no ubuntu testing there)

  I tested the following cameras
  Bus 002 Device 003: ID 046d:09a1 Logitech, Inc. QuickCam Communicate MP/S5500
  Bus 002 Device 004: ID 0471:2038 Philips (or NXP) 
  Bus 002 Device 006: ID 041e:406d Creative Technology, Ltd 

  (I also tried with ubuntu 10.04)

  Most similar bugs have been "solved" in the past by installing new kernels - the above was tried with the most recent at the time of this report:
   3.2.0-25-generic #40-Ubuntu SMP Wed May 23 20:30:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

  This computer has USB3 ports as well as USB2 ports - I have tried a
  variety - apport should show the Logitech plugged into a USB2 port.

  These cameras work on other compurters running 10.04 - if I had to
  guess, this is the only computer I have with USB3 ports - so is it a
  USB controller driver issue?
