Triple display dock - Ethernet and sound not working


I have just received my new USB-C 3.1 triple-display dock.

When I connect it to my XPS13 9360 at does complain about some USB device not working properly, but:

The Alt-mode video output is working fine, basic USB ports are fine too.


  1. The audio devices don’t seem to show up in Windows
  2. If I plug in ethernet I get blinky lights on the socket, but no connection and no device showing in Window.

I installed the Displaylink drivers. Are there other drivers required and where do I find them?

Thanks, my dock is at work so I’ll run the test app on Monday and come back to you.


I sent the requested plugdebug output to

What I find is that if I boot up my laptop with the dock attached then everything works OK, but if I connect the dock to my laptop whilst it is running then I get the USB error and my ethernet and sound doesn’t work.

Since I come and go from my desk for meetings it doesn’t work for me to reboot my laptop every time.


Thanks for the update Steve. I’ll look for the file you sent to us and be in touch directly via email.
