I manually put it into Accessibility, but no luck getting my monitors recognized: they don't even appear on the "Display" in System Preferences.

Puzzled.

We have identified that part of Dell D6000 docks produced between mid 2018-mid 2019 contains USB Hub firmware issue that was uncovered by macOS Catalina 10.15.1 release.

There is a for that.

Please update your dock hub using "Dell Firmware Update Utility":

Submit the logs to who? email?

I am running the latest 5.2 driver, Catalina 10.15.1 and I get the same as many others. Nothing shows up in my Screen Preferences and my screen is black.

My kext is showing loaded properly and notorized. I disabled SIP and touched /Library/Extensions as well. I don't get any popup about allowing access for Screen Recording and it doesn't show any apps listed for Screen Recording in my System Preferences->Security->Privacy.

I am willing to try anything at this poing.

Hi Signal,

Please attach them to the post, it will be accessible only to DisplayLink team.

I hope that you have the latest 5.2.1 drivers installed:

Hi Signal,

It seems that you don't have DisplayLink docking station connected.
It is visible in "About This Mac"->System Report->Hardware->USB tree.

Can you check the usb cable or power cable?
How the dock behaves on Windows?
Are other devices like mouse connected to the dock working?
