Hey Maldon, thanks for the setup. Got all working well using a Gigabyte Z590 UD (not UD AC) except for the USB ports. Tried to run the USB mapping tutorial, but no ports respond except to the usb 2.0 ports on the board back plate. Other ports do work before booting into MacOS. I've set BIOS settings as you specified. Anything else I can try, I'm stuck with only two ports working. Link below for my RunMe dump (IOReg dump failed though. Too large to upload). Muito obrigado!
