My uGreen 9-1 USB-C (90912) dock worked beautifully for one session (a couple days). Then, after undocking (took my laptop to the office) and reconnecting my laptop to the USB-C dock, both monitors started to say "no signal detected". I returned and purchased a replacement model of the uGreen (90912) dock, tried that one out and nothing changed. No signal detected.
I have uninstalled - rebooted, and reinstalled/re-configured/rebooted again the DisplayLink 1.8.1 driver. Nothing has changed.
I've followed all the troubleshooting suggestions. When I run the System Report and look at USB devices... What I notice is that the USB-C hub doesn't show up in the USB Device Tree (see attachment with screenshots), however, I do notice that *any* USB hub - whether it works or not - does not show up on the Device Tree.

I sent an email to support with my question a couple days ago and have yet to hear back. I will share the results of my help request in here once I hear back. In the meantime, any thoughts on what might be the issue?/
