I suspect the plug in the camera as I have the same problem. Am using a card reader. Can see a loose pin in the camera connector and have replaced the cable with same result. otherwise a good camera.
The problem may be with the computer. Have you tried connecting the camera to any other computer? If it is the camera, you might just want to pick up a cheap card reader and pop your SD card into it. Multi card readers sell for $5-$15 and will read most of the flash cards that are out there today. Jid
