So, recently my two usb ports are not working. The port closest to me is completely unresponsive and the other works on occasion. Usually it will work for about a minute, though my ipod registers as being connected to a 1.1 usb and not a 2.0, and then return to being unresponsive like the other one. I have already tried resetting PRAM and SMC and to no avail. I am basically assuming that the hardware is broken and that I will have to buy a new logic board or a new mac in order to have working usb ports again. Does anyone else have another idea for me?
