Hello David,

Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.

Are you using the Thunderbolt 3 cable that the dock was provided with to connect it to you MacBook Pro? Or are you using a third party cable?

I recommend to reset the dock in this order and see if it helps: If you haven’t already done so, fully unplug the dock from all devices, power, and Thunderbolt 3 cable to the host computer. Wait about 30-60 seconds, then reconnect the power cable first, Thunderbolt 3 host cable next, and USB devices last. Sometimes a reset in this order can resolve this kind issue.

If connecting the dock with no external accessories attached (no USB devices plugged into the dock, etc), does the issue still happen when just connecting the dock?

If the dock connects again as expected with no attached accessories, begin to connect your devices again one by one and see if a particular device/USB port on the dock causes the issue to happen again.

It’s possible there may be a hardware problem with the dock that is causing this error, but it may also be a particular device is trying to draw too much power from one of the ports.

Please don’t hesitate to let us know of other questions.

Thanks again for contacting Plugable support and best wishes!
