This starts to be a long story with many trials... but that's the beauty of Hackintosh !
- When I boot with fresh EFI OC 0.71 from your Mini Guide with a USB key initial boot is OK as I can start to load the OS.
Then when I reach login screen on BS or Monterey no more mouse (I see immediately that the mouse is disappearing during the boot process as the mouse has lightning inside that goes off).
And then at loginscreen I see that keyboard is no longer working. Furthermore, no USB port are available.
The Os try to find Bluetooth keyboard and mouse but obviously does not find any.
- Yes XHCI Handoff is enabled.
Basically I boot with the same BIOS settings for my existing working 0.70 EFI updated to 0.71 AND with the freshly created EFI OC 0.71 from your mini Guide.
One give me fully functioning mouse.
The EFI created with your mini Guide OC 0.71 leads to mouse/keyboard/USB ports not working.
If you put that EFI on a dedicated hard drive and not a USB key same problem occurs.
That's why I am really confused...
EDIT: To further investigate I created again from your Mini Guide a fresh EFI OC 0.70 USB key... and Boot is fine, keyboard, mouse and USB Ports are OK.
Therefore I feel there are some changes somewhere between EFI 0.71 and EFI 0.70 that leads to non working USB ports when you boot from fresh 0.71 EFI. This does not occur when you update your 0.70 EFI to 0.71 one.
Hope I have been clear enough, as it is not always easy to describe the problem and things investigated
