Hello. I've been using an 8 gig memory stick and webcam in the front 2 usbs on my pc with xp on it. The webcam has worked for about 4 years with no problems and the memory stick usb has worked for 3 months perfectly fine. Then the webcam stopped working. I was getting a message saying no webcam present. It wouldn't work on msn or if I opened the make video software it didn't see a webcam there either. Its like its simply not plugged in but it is. I then tried to access my memory stick and got the message usb device not recognized. So I plugged a game pad in and that worked fine. I plugged the memory stick in the back usbs and it still didnt' work. I read a forum and used software to delete the usb drivers but that didn't get it working either. I looked in hardware manager. The webcam is shown as working correctly but there is no sign of any usb there. The webcam doesn't work though so don't know why device manager says its working. Can anyone suggest any other way to fix this problem.
