labtec webcam

[Al Bayrouni]

I have a labtec webcam
When i use (for example digikam), there is no device detected.
I am sure I need a driver for the webcam
But I didn't find it
My question is, Is there any driver available for labtec webcam

Here is the output of lsusb:
Bus 003 Device 002: ID 046d:0921 Logitech, Inc. Labtec WebCam
