I was seeing the flash drive not detected issue on certain ports before I used the SSDT, but now it's detected no matter where I plug it in. If you don't see USB2 devices on the USB3 port, it makes me think there is a missing SSxx entry for the corresponding HSxx USB 3 entry. I noticed your device on the front panel is HS10, but on my MB HS10 is on the rear at the bottom. Looks like there must be some differences between your MB and mine, which means the SSDT may not be a perfect match for you. Mine is a Z390-A Prime too, so IDK. Since you're already using IOReg and are this far along in figuring out how your devices are identified, you may as well just go ahead and go through every physical port with a USB2 and USB3 device and take notes as to their SS/HS identity, then edit the SSDT.dsl file, then export to the SSDT.aml file and you'll have your own perfect SSDT. I'm surprised it doesn't match already though!
