integrated webcam stopped working

[ahmethungari]

Hi,

My integrated webcam stopped working (probably after updating packages, may be kernel). It is not found by cheese (no device found) or skype. It is not listed with lsusb or lshw, and there is not /dev/video*

Thanks in advance

Here are summary of my system
