My brother had this problem, shortly after this error his phone stopped charging all together... I hate to say it, but you may just have a broken USB port.
(As of now, mine won't even charge... its not recognized by the computer and the charger does nothing... I haven't found a solution besides using a second broken prevail, with a working usb port, to charge my spare battery)
Fortunately, it couldn't have come at a better time
on black Friday Kmart is selling the prevail for $30!
If you do solve this, and it turns out not to be a broken USB, please post back with what worked for you.
