HI
I have been having problems getting USB ports to work.
I have installed macOS Catalina using USB 3.1 Gen 2 Type A and currently using this port with a splitter in order to use mouse and keyboard
I have slimmed down kexts , and SSDTs and tried your method but couldn't get any ports under XHCI@14
I have also tried to make a USB inject specific to my MB but again IOReg shows no ports under XHCI controller.
Asus Rog Omega latest BIOS has no option under USB configuration to enable XHC Handoff . There is an option of ( mouse and keyboard simulation - enable / disable ) I tired on both setting no luck
After refreshing BIOS and clean install , Hackintool can now pick up USB 3.1 gen2 ( although different USB controller ). However , XHCI still not activated and not showing ports as per IOReg
As it is new build , it is running Windows 10 Pro smoothly and all USB ports working there. So its not a hardware issue , I guess .
My BIOS setting is copy past of KGP guide
Any ideas of what to do next , please
