I have a slim PS3 and all of a sudden my USB ports stopped charging my controllers. The ports will charge my cell phone however not my controllers. I have purchased a new controller thinking this would resolve the problem and it did not. I purchased a new USB cord and this did not resolve the issue either. I have tried resetting the controllers as well. I have been able to charge the original controller that came with the system via my computer and it works because it has been synced with the system however with the ports not working I am unable to sync the new controller. I tried a system reset today and now its asking me to sync the controller via the USB cable however they will not sync. The system has never been opened up and Im leery of doing so. Any advice??????????????????
