USB webcamera

[G2]

Hello

how can I make my USB webcamera Logitech Notebook pro to work.
I am using knoppix 3.82, and I installed gnomemeeting. Gnomemeeting works
just fine, but if I want to choose video, it doesn't recognize my camera.
And light on camera is all the time on.

Thanks for help

P.S: sorry for my bad english :)
