TBT3-UDZ rear USB ports inactive on wake w/ HP Spectre x360 13

I have the TBT3-UDZ dock connected to an HP Spectre x360 13 (model 8NS97AV).

When the laptop resumes from sleep, the rear USB ports on the dock do not work.

If I unplug the Thunderbolt cable from the dock to the laptop, and plug it back in, then the dock rear USB ports start working again.

Is there a way to have the dock rear USB ports work normally when the laptop wakes up?



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

We have a troubleshooting tool that helps us find out what is going on in situations like this. Please plug the dock into your computer, then go to this page and follow the instructions there:


If possible, I’d like to get a set of the diagnostics from when the USB ports are in a non-functional state. Please mention ticket # 326470 when emailing the results.

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

Thanks again for contacting Plugable support and best wishes!
