Webcam configuration

Hello to everybody !!!

Im writing because i have a little problem to configure my Webcam.
Im using a notebook with an incorporated camera, the problem is that it seems to be detected ( lsusb here ):

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 004: ID 0402:5602 ALi Corp. Video Camera Controller
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

… and configured in /dev/video0

In fact when I try to start using the camera ( like Skype or aMSN or using cheese ) the indicator of activity led brings on and seems to be work but quickly lights off and nothings happend, in cheese i see something like a Old TV Antenna difussion …

Apparently the camera its accessible because of the led … but i dont know how to continue the configuration.

Im running openSuse 11.2. Help would be appreciated!!

Thks a lot!!
