Ok so I got my Droid X about a week ago and I've been using the charger that it came with. Ok so when I have the USB cable plugged into the wall charger then my phone will charge. But when I plug the same cable into my computer or xbox, my phone will not charge. Can anyone explain why or help me out? I have tried multiple ports in my computers and my xbox and I've even used my old USB Cable that still fits this phone but it will never charge on either of them.
