pro 9000 - windows connects then disconnects usb

When connecting web cam, I hear the windows ding, will see the web cam pop up in control panel briefly, then hear the disconnect ding, and its gone.


I have had this working before with just using windows 7 basic drivers.  

Ive tried fresh/clean install, using logitech latest drivers.  No luck

Tried another usb port, cam worked briefly, strange,  then just disconnected again.

I have 9 different usb ports.


Im pretty good with this kind of stuff, but just cant figure why windows wont see this thing and keep it.  HELP!

Hello stoenr,


Based on your description, there's a chance that there is no power going through the cord on the USB end of your Pro 9000. I would recommend that you try to test the webcam on a different computer. If keeps disconnecting there, please send an e-mail to your local support team. They will help you check if your webcam is under warranty and, if applicable, to assist you with the replacement process.


I hope that you find this useful stoenr, and that everything works out well.

Thanks Paulina, I thikn you are right for the most part, I think there is a broken or shorted wire somewhere that is causing it to work randomly.   Purchashed a new c525  will see how she goes.  Thanks again for quick reply!
