D6000 not detecting S2721QS monitor

[AlbanRampon]

Hello,
There is no trace in your logs of any Dell D6000 device ever being connected.
I see some Plugable DL-3900 based device in March.

1. Did you collect the logs with the dock connected, powered and all cables in?
2. If yes to 1, does the front right white LED light up when you plug the Dell D6000

3. If no to 2, can you try to plug the D6000 using the included USB-A adapter to a USB-A port and in that case, does the light come up?
4. If yes to 2, can you plug a mouse/keyboard/USB3 flash drive to the dock and it works?

The dock should show in Device Manager in Graphics Adapters and in Network Adapters.
If there's nothing in Device Manager (like I can see in logs you posted), and there's no device in error, then it's not a driver issue: Windows need to see the device and its ID to know what driver to choose.

Thanks,
Alban
