How to Fix USB3 issue on Ryzen based APU Laptops​

 
Commented when guide was still WIP but kindly make sure that Ryzen XHCI Fix is loaded before USB Toolbox Map and USB Toolbox kext.

Also you might have to disable USB Toolbox and USB Toolbox Map to boot into installer.

Alternate fix is to disable one of the xhci controllers using Smokeless UMAF.

You can also force macos to boot without using any fix by plugging in usb device into every port. Might take a few seconds but it boots.
