Bug Description

As described above. I start Ubuntu and the webcam-LED indicates that the webcam is active. After first real usage, for example with cheese or skype, the webcam-LED turns off.

It's the same problem with the latest kernel (uname -a gives: Linux cerveau 3.3.0-999-generic #201203300409 SMP Fri Mar 30 08:10:21 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux).

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

I've bought the cam several days before I've posted the bug report so I can't tell you if the issue happened in prior Ubuntu releases. Will test the mainline-kernel later on.

It's the same problem with the latest kernel (uname -a gives: Linux cerveau 3.3.0-999-generic #201203300409 SMP Fri Mar 30 08:10:21 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux).

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

Still an issue in 13.10. I'm sorry but I can't try to install the latest upstream kernel, because I don't want to risk to lose my data.

Alexander Kallenbach, if you backup your data, no risk of loss would exist. Hence, 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 kernel 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:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

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:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

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.
