USB port does not work on computer :(
Ok, so I have an extremely beat up 3rd gen iPod nano, but the only way I can charge it is putting it on an iPod dock, which will charge it but not play music while it on the dock (you can connect a stereo plug into it and works fine.) In addition, it is not recognized by the computer when connected via usb and does not charge. How do I fix?
TL;DR: charging works only when connected to iPod dock, data works never... why/what do?
EDIT: The cable is not faulty, it works with other devices, and I have tried other cables.
Is this a good question?
