I purchased a WEBCAM (for dummies). I unplugged my digital camera (that works in this USB port). I plugged in the camera and it does not see it. I plugged back in my camera and it works fine. I also tried my thumb drive, works fine.
I plugged it into my laptop and the camera was reconized.
I need help in figuring out how to get my XP system (with SP2), to find my camera. The WebCam for dummies help center will not support me with this issue. They say it is an xp issue.

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.
