Stubborn missing mouse & keyboard in installer. What’s left to try?

[Charlweed]

I’ve spent hours trying to get mouse and keyboard to work from OpenCore 6.8 in MacOS installer for Mojave and High Sierra. I’m wondering if its really a USB issue at all, because I’ve tried everything I could find.

Before a drive failed, the PC ran El-Capitan via clover. It’s been Windows-only for quite some time.

 

CPU: Intel Core i7 3960X (Sandy Bridge-E)

Motherboard: ASUS Rampage IV Black Edition uefi

 Boot: OpenCore 6.8

 

I’ve tried:

    All USB ports, 3.0 and 2.0.

    Unplugging and replugging before & after installer starts.

    Adding additional USB mouse and KB

    Enabling/Disabling USB compatibility mode in firmware.

    Clearing NVRAM via OpenCore tool

 

In the ACPI dir, I’ve tried

    SSDT-EC-USBX-DESKTOP from OpenCore

    SSDT-UNC from OpenCore, & different one from Dortania

    +- custom SSDT generated from previous Clover installation

 

In the kext dir:

    +- XHCI-unsupported.kext

    +- USBInjectAll.kext

The other kexts are

   AppleALC.kext

   IntelMausi.kext

   IntelSnowMausi.kext

  Lilu.kext

   LucyRTL8125Ethernet.kext

  SATA-unsupported.kext

   VirtualSMC.kext WhateverGreen.kext

 

In the Drivers dir:

    HfsPlus.efi

    OpenRuntime.efi

 

In the config.plist, I’ve tried:

Kernel:

    XhciPortLimit enabled & disabled

    Kernel-Patch:

    +- IOHIDFamily Patch and from here

PlatformInfo:

    iMac12,2 & MacPro6,1

 

 

Any help would be appreciated.

TY!
