There were a few different models marketed under this name (WEBCAM for dummies). Did you install the software package before plugging in the webcam? The software contains the drivers that are supposed to get the webcam working.
These are older model webcams, so while I am not surprised that they claim not to support XP, it is still not helpful to customers, is it?
The manual actually states that it should work.
Try installing the software package first, then plug the webcam into a USB port that you have not already used for other USB devices, such as your thumb drive or digital camera.
