Many models of Logitech webcams stopped working as starting in v3.5-rc1. I was able to reproduce this bug with a Logitec C250. It's going to be a little difficult to bisect since I ran into a USB bug that does allow any USB devices to work. The USB bug was fixed in v3.5-rc3, and I was able to reproduce the webcam bug in that kernel. So to recap testing: v3.4 does not have this bug. v3.5-rc1 has a separate USB bug preventing testing of the webcam. v3.5-rc2 has a separate USB bug preventing testing of the webcam. v3.5-rc3 the USB bug is fixed and the webcam bug is reproduced. v3.5 daily still has the webcam bug. There is also a bug opened on Launchpad[0] against the Ubuntu distro. Hardware details and logs are available from there, or upon request.

It seems that many desktop applications, and the shell itself, are blocked on PulseAudio. PulseAudio is stuck in state "D": comatose. It's never a good sign when processes are in state "D".... I was earlier running 3.7.10 (Gentoo) and this bug didn't happen at all back then. Workaround is to hit Control-Alt-F1 to escape your unusable desktop, go to your text shell, start removing modules until you get rid of the offending sound driver, then hopefully that will snap PulseAudio out of its funk. Then, you can return to your desktop, and although it will be silent, you can use it again.
