New USB Raise Port Limit Patch for High Sierra

[RehabMan]

I have a general understanding question: If I disabled USB ports within my bios, do those ports usually disappear, because the bios then would remove the port from ACPI

It may, but the behavior would be BIOS dependent.
You should test it and see.

::edit:: nevermind. I had to go into Clover configurator and change

"Comment: change 15 port limit to 24 in XHCI kext (9-series) 10.13

Name: AppleUSBXHCIPCI

Find: 83bd74ff ffff10

Replace: 83bd74ff ffff15"'

to EXACTLY what you posted in the original message. Thanks!

Wonderful!
This fixed the issue on my Gigabyte GA-Z170XP-SLI + i7-6700k.

I have USBInjectAll in /Library/Extensions/USBInjectAll.kext, in /EFI/EFI/CLOVER/kexts/10.13/USBInjectAll.kext and in /EFI/EFI/CLOVER/kexts/Other/USBInjectAll.kext but I'm not sure which location is THE right location.

By the way, after copying USBInjectAll.kext to the paths above I've executed
sudo touch /System/Library/Extensions && sudo kextcache -u /
