    Wierd deal. I had been having an issue where the "second" USB port on my 15" 2011 mbp would sporadically go dormant, and would NOT reactivate until I rebooted or restarted the machine. Took it into Apple genius bar today, and they determined i/o board not getting proper voltage/current at ports. Part ordered. Anyone else had an issue with the USB or other ports going inop sporadically?

    Is this whilst just on battery, and not mains? when on battery only one of the usb ports will provide full power.
