Hello Warren,

Thanks for contacting us! We’re sorry to hear that some of the ports on your hub are malfunctioning. If you haven’t already, please try completing a full reset of the hub by following the below steps.

  1. Fully unplug the hub from all devices, power, and USB cable to the host computer.
  2. Reconnect the power cable first, USB host cable next, and USB devices last.

If that does not resolve the issue, please let us know. We’re happy to help walk you through the troubleshooting process further.

Thank You,
