OK -

"lsusb" shows your device:

"lspci", in this case, is irrelevant. Because you have a USB webcam, not a PCI webcam ;)

So what do you need to do?

You can Google for "Linux redhat USB 04f2:b016 Chicony Electronics web cam" (or anything similar), and you'll come up with a bunch of hits.

Including this:
http://linux-uvc.berlios.de/
<= Your webcam should be fully supported ... without any additional drivers or downloads ... for any Linux 2.6.26 or higher.

You can determine your Linux version by typing "uname -a".

You'll also need the Video4Linux 2 (V4L2) subsystem (which should be standard), and some v4l-compliant viewer (like "cheesecam").

'Hope that helps .. PSM
