Found a Logitech webcam that works on OSX 10.4 but not on Vista! Help?!

For the longest time I have been looking for a webcam that actually works
on a Mac Pro OSX 10.4.

Logitech just released a $100 webcam called QuickCam Ultra Vision. It
is one of the very few camcorders that work under OSX 10.4.

Now the problem is getting it to work under Vista via Parallels.

As instructed, I installed the Logitech software (Vista capable) and then
plugged in the webcam to my USB port. I went to DEVICES in Parallels
and enabled the Logitech camera that was already listed there.

Problem is, though Vista detected the USB connection and installed
the drivers, it will not detect the webcam itself.

Is this a problem with the current version of Parallels (3170) or is there
something I am doing wrong here?

Looking forward to hearing from those that might have an answer.
