You have the same motherboard as me so upload your EFI and I'll apply my USB port map as it should be valid for you too. That should help.

FIXED!
After much search in internet I found a wiki where explain possible prelim with power supply to usb in AMD mobos.
The solution is add SSDT-EC-USBX-AMD.aml in opencore folder ACPI and in config file.
I attach the file in this post.
