Help needed making sense of how to configure USB ports in Opencore on AMD Aorus pro X570

Managed to successfully install Catalina on my ryzen 3900x. I have the USB ports not being recognised. So I did try to read the trouble shooting guide to mapping the ports manually. To be honest I found it rather confusing. Is there anyone out there that could point to a clear guide for beginners or help me through the process with some helpful pointers. Much appreciated guys.
