Problem: A Motorola phone (specifically the W755 and similar series) will not charge on USB either ever, or after reformatting a computer. Applies to many Motorola phones, including Motorola Android, Motorola OS, Motorola Linux OS, Motorola iDEN, Motorola Symbian/UIQ, Motorola Windows Mobile® and Motorola i-mode devices, Motorola XOOM™ tablet.

Cause: Older Motorola phones will not charge while they have a data connection active. If you were able to charge before and reformatted, you probably no longer have the correct drivers that would allow your phone to charge.

Solution: Download the Motorola Helper Software so that the phone will know to charge rather than just use a data connection. (Note from the author: I know this sounds preposterous, but Motorola phone USB charging is messed up stuff).
