Webcams are a special class of usb device in that most, if not
all, use the VIDEO FOR LINUX driver (v4l) and as such have a
/dev address of /dev/video0
The *bestest* application you can currently use for these
webcams is xawtv. It is simple, easy, and works. If it
isn't installed, you can get the rpm from www.rpmfind.net, or, alternatively
get the source from sourceforge
The worstest application you can get is SANE. Unfortunately, it's the only one.
There is a klunky, poorly performing v4l library in SANE, that
sort of works. The documentation for SANE is attrocious, the
applications as written mostly don't work and are incompatible
with each other, and the config files as suggested (and
environment variables) are wrong. However, ymmv. It would
appear that the usb developers agree with my opinion. It would
appear that development-in-progress is occuring for usb
scanning devices, of which video style and photo style cameras
is at top of list. Expect flat bed usb scanners to foilow real
IN GENERAL two modules are required to get any webcam working

will cause all other modules, including videodev, including usb-uhci, to load.
It is, as simple as that.
Two classes of driver currently (andalways will) exist.
Drivers in the kernel
Drivers under development
The difference between them is that kernel drivers are
accounted for in the hotplug tree. This is to say, generally,
simply pluggin the device in, causes all necessary modules to
load for that device. Wheras, for the others, you have to use
good old modprobe,
