USB will charge phone when plugged into PC but will not recognize it as a device. I am guessing it is something wrong with my computer but I can't figure it out. I have done this before when I first got this phone and it worked. Plugged the USB in and it recognized it. But this time it will only charge it and will not give me the USB Connection option in the status bar. Downloaded Motorola Driver but after rebooting, that still didn't fix it. Please help!
