I hope Iím posting this in the right sub-sub-sub-forum (arenít all audio + video problems ultimately Hardware problems?)

When I run lsusb it shows me
Code:
Bus 001 Device 002: ID 05ca:18b3 Ricoh Co., Ltd Sony Vaio Integrated Webcam
And when I run GUCViewer or Cheese, it lists the video device as UVC Camera (05ca:18b3). Yet all I see is a black screen.

What must I do to, you know, actually get any picture out of this thing?
