Comment 4 for bug 1147729

Same issue on Ubuntu 12.10 64 bits, on a Lenovo Ideapad U410. I've been using the included webcam with Skype and Google Hangout with no issues. At some point in time, I noticed on Google Hangouts some update made the cam stop working.

So, now I test something like VLC to "Open Capture Device". The webcam turns on, but there's no image. Same thing on Skype, I test the video and the cam turns on, but no image. At some point, the camera disappears from lsusb and I can't see it there anymore.

lsusb:
Bus 003 Device 002: ID 04f2:b2e1 Chicony Electronics Co., Ltd

It's failing on linux-image-3.5.0-25 and linux-image-3.5.0-24. Booting with linux-image-3.5.0-23 makes the webcam work.
