Hello r/Hackintosh,
All of my USB 2 ports work with both USB 2 and 3 devices, my USB 3 ports only work with USB 2 devices, and therefore I can't use my USB 3 devices properly (With USB 3 port).
SMBIOS: iMac20,1.
CPU: i7-10700F (Comet Lake).
USB Controller: Comet Lake PCH-V Series 300 (0xA3F, 0x8086).
I used Dortania's OpenCore Install Guide.
The kernel extensions (kexts) I installed: AppleALC.kext, CpuTscSync.kext, Lilu.kext, RealtekRTL8111.kext, USBInjectAll.kext, VirtualSMC.kext, WhateverGreen.kext, XHCI-unsupported.kext.
I tried to map the USB ports using Hackintool:
When I used USB 2 device, all the ports worked (Both 2 and 3).
When I used USB 3 devices, only USB 2 ports detected my device (as described above).
Also, I read that: https://www.reddit.com/r/Hackintosh/comments/mzjvel/concerning_big_sur_113_usb_problems/
But similarly, When I try to map using IORegistryExplorer (According to OpenCore's guide), I get the same result.
My SMBIOS doesn't require ACPI renames.
XhciPortLimit boolean in config.plist is not affecting anything as well.
