Hello to all!

I have ubuntu 12.10 running on my notebook, which is a LGN450 with Radeon Graphics and a Built-In Webcam.
When trying to run the webcam ( LG HD Webcam ) via VLC, my system detects the camera(by making the webcam light turn on) but I have no image return.
I checked my
Code:
$ lsusb -d 13d3:5183 -v
and got the information the the uvcvideo is trying to run it, and obviously failing.

Does anyone knows how to enable my webcam and/or if the problem is the lack of driver to open it?
