USB port disabled after too much power.
I can't enable 2 USB ports. I attached a Asus Wi-Cast and it shutdown the computer and disabled 2 USB ports on the back of Mac Pro.
MacPro Mountain Lion
(only devices are mouse/keyboard. Also they wont work on the 2/3 usb ports on back)
- I reset PRAM
- I unplugged and held down power button.
- Open up Mac and held down the buttons on logic board.
