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?
Watch Question

Does your PC give you any errors when plugging the webcam in (i.e. unable to find drivers, unknown device...)

Also, do you have other USB devices that work fine on that PC?



Unknown Device is the error it gives...all other USB devices are recognized and work fine.
Have you tried it in different USB ports. I would assume so with the extent of fixes you went through already, but thought I would suggest it anyway.



Yes, I forgot to add that in my initial post....I did try the device on different USB ports...however, it keeps giving the same msg (device not recognized). It's just odd that it worked fine and now won't work at all....and works fine on other PCs that are the same make/model/hardware. Thanks for the quick responses! any more suggestions would be greatly appreciated.
After you plug in the webcam and you get the "unknown device" message, did you try to go to Device manager, click on the unrecognized device, and install the driver manually from the CD?

I've had a few issues in the past where the installation software didn't install the driver correctly, but manually installing the driver worked.

Just tried to manually install the driver from the CD...still getting the same error. I'm starting to wonder if this isn't just an issue with the camera...maybe an intermittent issue. However it did install and work just fine on the 2 PCs that I tested it on earlier.
Have you tried another model camera, if you have one, on the faulty computer. See if it gets recognized. The camera seems fine if working on other computers, then it must be on the computer somewhere and need to isolate it.

Good luck,



Ok...tried another model camera, received the same error when I plugged it into the PC.
USB printer was causing the issue...when it is disconnected the webcam works fine, connected and the webcam goes crazy.
