Hi,
You dont offer much information for us to go on. There may be
different
versions of this camera but i use them and they are enumerated just
fine.
Post all relevant information, BB rev, port, powered hub, os build
version
and where it came from, etc.

I have posted this here before.

BeagleBoard webcam stats:

dmesg | tail -- will list what was detected when the webcam is
plugged in.
lsusb -- should show the device id and description if it was
picked up.
lsmod -- should show the modules associated with the device.

if it is a UVC model camera you may need to load the uvcdriver
root@beagle:~# modprobe uvcvideo --- unplug then replug the webcam
and look again
using the above.

I believe uvcvideo comes with kernel-module-uvcvideo

look for something similar:
