My usb port will not connect to any devices.
When I try to use my usb port a pop-up window says it has been disabled because a device connected to it is drawing too much power. And that the usb will be enabled after removing the device. But this does not work. I've tried this and the usb port still will not charge or recognize any device, ext hard drives, ipod, ipones, etc. I've tried booting in safe mode; tried resetting the SMU; tried disconnecting the battery for 10 minutes and rebooting. There is very little else on the web other than the above suggestions.
