It is my understanding that all Dell Precision M4500 laptops come with an integrated webcam. I can physically see the webcam above the screen, but neither windows 7 nor ubuntu operating systems recognize the webcam at all.

Reading other posts, I have checked 'lsusb' and 'lspci' without any luck of finding the webcam. I tried changing 'gstreamer-properties'. I tried various applications like google hangout, skype, and cheese.

Any suggestions would be helpful.
