Dell UltraSharp monitor with USB-C dock has no USB-C "hubb" in Ubuntu

I have a Dell UltraSharp monitor with a built-in USB-C "dock" and I use the UBC-C cable from the monitor to charge (and connect the monitor) on my Dell XPS 17.

The USB-C "out" is working thus, and I get the display through it, but all USB, and the extra USB-C ports on the monitor "dock" are dead, or they are power only.

I've updated everything I can find and I am on Ubuntu 22.04.

Running `lsusb` I can see a bunch of "root hubs":

Bus 008 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 007 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 0bda:5510 Realtek Semiconductor Corp. Integrated_Webcam_HD
Bus 001 Device 002: ID 27c6:533c Shenzhen Goodix Technology Co.,Ltd. FingerPrint
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The list is the same if I unplug the monitor so it would seem that no USB hub/dock is detected over the USB-C "out" cable from the monitor...

Any ideas how to get it running?

Did you ever solve this issue?

I sometimes seem to run into the same problem when connecting my Dell P2723QE screen with my Dell XPS 13. When I connect my Apple keyboard (which is in itself a USB hub) to the screen, it sometimes isn't detected. I think maybe this only happens when something is plugged in to the keyboard's USB ports.
