Usually, when I plug my phone into a computer the phone sees the computer and puts up a prompt for Mass Storage mode, Tether, or charging.
I know the phone is ok because I have seen this using my work computer.
At home, no prompt comes up on the phone when I plug the phone into the computer.
My computer is Windows 7, 64bit.
Is there any way for me to diagnose the computer to find out how to fix it without a rebuild?
I just tried different ports: each time the phone beeps and charges but no prompt.
Device Manager shows a bunch of USB devices, no errors.
