Have you fully charged it with the wall charger then tried it on USB? On many devices when the battery completely dies you have to charge it with a wall charger. Then the USB will be able to charge it after it is fully charged again. A USB cable doesn't output as much power as a wall charger, so if the battery is really low it won't have enough power to charge it back to full.
