Asus P8H67-M EVO High Sierra OpenCore

Hi everyone!
I managed to boot the installer by installing DuetPkg and forcing Legacy BIOS. High Sierra installed just fine.
Everything running smoothly (even sleep) except USB3 ports.

They do work in the Mountain Lion partition, where GenricUSBXHCi.kext is installed in /S/L/E/. OpenCore is apparently unable to load it from Kernel->Add

I tried to install it in /L/E/, but it's not working. Any suggestions?

I think you should try to map your USB ports.
 
I already did. I have renames for EHC1 and EHC2, but the USB3 controller is an ASMedia (PCI0.RP05.PXSX) and there is no way I can get it work, even adding its IOService Path in USBMap.kext
 
Got USB3 working with mXHCD.kext
I had to modify the IOPrimaryMatch to work with my PXSX, but it seems much more stable than GenericUSBXHCI.kext

One last thing that’s not working is “Bless”. I tried to enable NVRAM Emulation, but still nothing.
I'm sure I'm doing something wrong, but there's a part of the Dortania guide about old OS's (I have 2 SSD's, one with 10.13.6 and one with 10.8.5) which is unclear to me:

"Do keep in mind this requires the nvram command to support the -x flag for this to work correctly which is unavailable on macOS 10.12 and below. If you are installing macOS 10.12 or earlier, you need to copy nvram.mojave into the same folder as LogoutHook.command, which fixes this by invoking it instead of the system nvram command."

What and where is "nvram.mojave"?

Managed to write nvram.plist following dortania guide, but still choosing the boot drive in System Preferences has no effect
 
can anyone help me?
I cannot choose the default boot drive, not even with Ctrl+Enter in picker and AllowSetDefault set to True. I read the Dortania guide and OpenCore configuration pdf many times, but I really don't know what else to try.
nvram.plist and EFI folder attached

Try this EFI on a USB drive first. It's a copy of what I have running on my H67N-USB3-B3 build, at least to see if you can boot with it.

Nope... Kernel Panic. This mobo only boots with DuetPkg.

Native NVRAM is not working either, only emulated

Did you enable DummyPowerManagement under Kernel?
