Single Laptop, Multiple Dell WD19DCS Docking Stations

Anyone else try, or rather, having issues (maybe even successful) getting a single laptop (Dell Precision 7560) to connect to 2 different (not at the same time) same model docking stations?

I have a Dell Precision 7560, Windows 11 Enterprise -- latest drivers, firmware, etc., on both docks and the laptop. My experience is the same each time using the WD19DCS.

1. Connect to dock at work -- no problems.
2. Connect to dock at remote location -- Everything works, except Realtek USB GbE Family Controller (Device Manager shows <!> Unknown USB Device (Port Reset Failed) within the Universal Serial Bus controllers section).
3. Perform the exercise below to get the GbE controller to register properly.
4. Connect to dock at work -- no problems.
5. Connect to dock at remote location, repeat step #3.
6. Connect to dock at work -- no problems.

WASH, RINSE, REPEAT.

If I perform the following steps, I get the GbE controller to work:

1. Disconnect both DP cables that connect the dock to the laptop (laptop remains on).
2. Remove problematic <!> Unknown USB Device (Port Reset Failed) from Device Manager.
3. Disconnect power from the dock.
4. Press and hold the power button on the dock for 30 seconds.
5. Reconnect power (power light rapid flashes 3 times).
6. Reconnect both DP cables that connect the dock to the laptop.
7. GbE controller works!

Prior to this exercise, I've been able to successfully use the following configurations -- laptop connected to WD19DCS at work and:

• WD15 elsewhere (with a secondary charger plugged into the laptop).
• WD19TB at remote office (with a secondary charger plugged into the laptop).
• WD22TB4 at remote office (with a secondary charger plugged into the laptop).

I've tried everything I can think of:

• Swapping, switching, disconnecting, etc., every connected device -- same result.
• Remove driver set manually (PNPUTIL) and via MSI/EXE and re-install/repair -- same result.
• Switched docks (I.e., moved work dock to remote office) -- same result.
• Switched power supplies between the docks -- same result.

Things I am unable to attempt:

• Connect problematic dock to another laptop (unfortunately, I don't have another dual DP ported laptop).
• Downgrade firmware on the problematic dock (at least I wasn't able to locate how that might be performed). I did upgrade the firmware to the latest as part of this exercise, but it didn't change anything.

Problematic dock is under a Basic (exchange) warranty, but since the problem is "sporadic", it doesn't seem (to me) a replacement is necessary at this juncture.
