The computer recognizes the phone and I can navigate to the pictures. When I start to copy the pictures to the computer, I eventually get a a "device not recognized" or "device not functioning properly" and the copying quits on me. I'm using a cable that has worked with no problem before and I've tried all the USB ports. Both the phone and the computer have gone through updates since the last time I did this in April. I'm at a loss. Anyone have any ideas?
