One of my USB Ports don't work. Tested power with USB Meter.

One of my USB ports don't work on my MacBook Pro. Tested the power with a USB Meter.

  • 1st port has power.
  • 2nd port has no power at all

Any device I plug in doesn't work on the 2nd port.

Is there anything I can do to fix this issue?

There is a small fuse link just behind the USB port that you have burnt by plugging in an over powered device. Make sure you used the correct power unit for the device as well as make sure you use a surge suppressor for both your computer and the USB devices.

If you have access to a self powered USB hub and plug it into your bad port and then plug something in to the hub the device should work then.
