Unhappy /dev/video0 is gone

Hi there,

I was trying to setup my webcam and the internal mic for some time on a Dell precision m4500 with Ubuntu 12.04.2 LTS (GNU/Linux 3.2.0-38-generic-pae i686). Enabled in the bios but no way to turn it on.

Then without any intervention from me (after a kernel update, my only valid hypothesis), one morning the webcam and the mic works...

Today /dev/video0 is gone, and the mic doesn't work anymore...

Any clue ?

My fault, the webcam was desactivated in the bios and its microphone is on the same bus.
