Hi automised_matt,

Thanks for the update and additional checks.
I'm going to discuss your case and further actions with engineering - let's continue the discussion via the support ticket you have raised.

Regards,

I found my problem - and it is my fault. My monitors have 2 x DP ports in each. I did not realise that one port was DP In and the other was DP Out (for daisy chaining). I though both were DP In ports. I had, by chance, plugged the DP cables from the dock into the DP Out ports on both monitors, instead of the DP In ports. That is why they were not registering as being connected to the dock. Once moved to the DP In ports on the monitors, everything worked again... 🤦🏻*♂️

Sorry for any wasted efforts...

Having the same problem with that anyone in this thread (beside automised_matt

):

-Dell D6000
-Macbook Pro M2 Pro 14"
-macOS Tahoe Version 26.4.1 (25E253)
-DisplayLink 16

I tried everything: unplug/plug reboot, clean, reinstall....
Was working fine (with 2 monitors) and suddenly stopped working. In System Report I see my D6000 connected to the usb port:

But the only thing that the Dell D6000 does is charge the computer (no monitors, no audio/pendrive).
Does anyone have a clue of what could be happening?
Thanks in advance

Hi ginopalazzo,

It seems none of USB 3.0 devices appear on the bus, which confirms your observations (no monitors, pendrive).

Are you able to test your dock connecting to another port of your Mac or different Mac / PC?
If the problem persists it could be a hardware fault.

Regards,
Szymon
