After upgrading to kernel 3.1.3 my uvc webcam stopped working. It is recognized but cannot send video data, even if the integrated microphone works well. Downgrading to kernel 3.1.2 solve the problem.

This is a part of dmesg, errors appears only with kernel 3.1.3:

[ 9248.385816] usb 1-3: new high speed USB device number 6 using ehci_hcd
