Received Thunderbolt 3 dock for my X1 Yoga 2nd Gen.
It's charging the Yoga, the two displays are working.
ALL the USB and ethernet ports are not.
Did the updates, restart, repower of dock and Yoga.
I know the ethernet is good because I have been using an USB to ethernet directly connected to the yoga.
Yes I disconected the USB to ethernet adapter when trying the ethernet port on the dock.

Did you ever find a solution around this? I'm having a similar issue with a thunderbolt 3 hub. everything works except for the ethernet port even though it's active with lights blinking, laptop does not register ethernet adapter.
Anybody from lenovo got some insight around this?

I actually had to unplug the dock and remove the device drivers for Enet, USB and dock. Shutdown the Yoga, connect the dock and boot the Yoga. The Yoga identified the new devices Enet, USB and dock, it loaded the the device drivers (as they were still on the machine). And sure enough all the ports worked.
It appears that the first installation of the dock messes with the USB host process (can't find it's interface ID). Because on the re boot the dock installs first then Enet and UBS.
