Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.
If you haven’t already done so, fully unplug the dock from all devices, power, and USB-C cable to the host computer. Wait about 30-60 seconds, then reconnect the power cable first, USB-C host cable next, and USB devices last. Sometimes a reset in this order can resolve this issue.
Please don’t hesitate to let us know of other questions.
Thanks again for contacting Plugable support and best wishes!
