This is certainly pushing the limits of my knowledge and ability, but here goes nothing:
This is what I have done so far. I'm not sure what to do next.
I don't see any active DSDT.aml or SSDT.aml files associated with this installation.
First I checked the bios on my GA-Z170MX Gaming 5 running OS 10.14.3. The only thing I could find was under >Peripherals>USB>XHCI handoff>enabled/disabled I didn't find any other choices.
Then I checked ACPI under Clover Configurator and changed it like this:
I see these kexts in >Library>Extensions:
FakePCIID_XHCIMux.kext
GenericUSBXHCI.kext
FakePCIID_XHCIMux.kext
FakePCIID.kext
USBInjectAll.kext
Some relevant shots of my config.plist:
And then some from IO registry:
And lastly, the >About this Mac>System Report (which shows some devices connected through the usb3 bus):
I don't see any active DSDT.aml or SSDT.aml files associated with this installation
What do I do next, please?
