Good information. That indicates the phone is okay. What kind of cable are you using? Have you tried more than one USB port? You said it plays a tune when you unplug it and replug it. If so, that means the computer is seeing it. I have had trouble with external drives that the USB port could not supply enough power to. I doubt that would be an issue here but it is another thing to check. If you have another computer that works at all, try connecting the camera to that just to see what happens.
