Need help troubleshooting USB on B450M Steel Legend

Hardware Used

In conclusion, all of the USB does show up and detected correctly, however only 4 of the USB works from XHC0.

I tried following OpenCore AMD Mapping Guide, they mentioned using AMD-USB-Map.kext to manually map USB, I've taken a look into my DSDT but there's no renaming I need to do and USB are correctly detected. But one thing that is suspicious is that in my DSDT, there's extra HS03 and SS03 which I have no idea which port it maps to.

I can confirm that the other USB Ports does work, as I have tested them in a Ubuntu Live USB.

I am stuck here, not sure what's the next step to fix this issue.

Here's my EFI Folder and Dumped DSDT: https://github.com/marcustut/Hackintosh
