Gigabyte B550 Vision D (Thunderbolt 3) + AMD Ryzen 7 3700X + AMD RX 5600 XT

@CaseySJ, that should be the one I re-uploaded, but I have tried again:

That's better, but we see that only the top half of the Thunderbolt devices have been renamed, and not the bottom half. This may or may not be okay. Let's connect a Thunderbolt device -- both hot-plug and before boot -- to see if it works.

@CaseySJ here's a TB turned on at cold boot, and one with hotplug, seems like there's no difference.

Correct -- Thunderbolt device is not appearing in both cases. What is the make/model of the TB device?

Are you using BIOS F2?
 
I am using a Lacie D2 Thunderbolt 2 Enclosure for these tests. The drive appears in Windows 10. I have also tried an Areca 5026 Raid enclosure as well.

I also have a TB2->Ethernet adapter, that I have tried previously, if that is of interest.

I am using the F11 BIOS, that the board came with.

Two suggestions:
  • Try connecting a USB-C device instead of a Thunderbolt device. For example, a USB-C flash disk. Does it work?
  • Then downgrade the BIOS to F2 because it does not contain Resizeable BAR support. Then first thing we'll need to look at is IOReg file.
If we cannot get this board to cooperate, it may be time to consider returning this board in favor of the B550 Vision D.
 
Here is another with the same Lacie D2, where I booted into Windows 10 activated the drive and rebooted into Big Sur

Still nothing connected in macOS.

Yes, with USB-C drives it works.

Here is a reg with F2 BIOS and cold boot (BT doesn't work now btw.). Still the same.

Okay, now the GPP1 sub-tree is properly named by DSDT, which is an improvement! The B550 Vision D SSDT should work. Let's give it a try (attached; note the exact file name):
  • Copy file to OC/ACPI folder
  • Add a reference in ACPI section of config.plist
  • Reboot and let's look at IOReg again (want to see if all sub-devices are named properly)
Regarding Bluetooth, don't worry because the BCM94360NG is coming. A small change to USB map might also be needed (not sure yet).

Additionally, you have a Thronmax MDrill One Pro microphone connected to one of the external USB 2.0 ports. Try moving that to the other external USB 2.0 port.
