Question : Problem: Logitech Webcam not recognized XP

I have a Logitech QuickCam Pro 9000 that I'm having some issues with...initially it installed correctly, I was able to configure and use the webcam...worked for about 1 day, then XP wouldn't recognize the device. The webcam won't work (on this pc) now...here is what I've done so far:

-Tried the webcam on other PCs (same exact hardware, OS, etc)...works fine on the other machines

-Windows repair

-Uninstalled/reinstalled Logitech drivers & software

-Uninstalled USB ports via device manager, rebooted and let Windows reinstall them

Web cam: Logitech QuickCam Pro 9000
OS: Windows XP Pro SP3

Any ideas?

Answer : Problem: Logitech Webcam not recognized XP

USB printer was causing the issue...when it is disconnected the webcam works fine, connected and the webcam goes crazy.
