I have a friend who has a Sony digital camera and she is having problems when she connects it to her USB port. If she connects it and turns it on when the pc is switched on it freezes and then all she can do is reboot her machine. If she connects the camera, switches it on and then powers up her pc it works OK and we can look at and transfer pics from camera to pc. If we disconnect it the pc carries on working. She is running Windows XP Pro. She has an Intel motherboard, I have re-installed the drivers for the USB ports. Anyone have any other suggestions that I can try?
