Very interesting, that would explain why my usb devices connected to my dock didn't work in macOS when I plugged it in to the USB-C port, but the same devices worked in windows. I just did a quick check and didn't look at the Ioregistry. But while the port is disabled for usb connectivity at the moment, displayport tunneling surely is working in macOS and it works well.It looks like the new drivers disable the USB ports. It shows up with an AppleAMDUSBXHCIPCI entry, but with no ports:

And whereas in earlier Big Sur versions you could plug in a USB stick or other device into the USB-C port and it'd work, and sleep was broken even with the GPU disabled unless the controller was disabled, neither is true now.
Seems like Apple is still doing some enablement of the AppleAMDUSBXHCIPCI class... and this is an early beta after all... I wonder if until they fully enable this new USB driver for the radeon cards, if in the meantime we can find a way to allow com.apple.driver.usb.AppleUSBXHCIPCI to load? Don't know if it would work, but just a suggestion.
