OMG UNBELIEVEABLE
Ive earlier tried to boot from every single USB port with no luck and stuck at the UsbHostRessources.
NOW ive tried the USB 3.1 port at the back and im able to get to the Installer where you first select the Language.
But now my mouse and Keyboard doesnt work. Now i understand why i was earlier not able to get to the Installer, because my f.... USB ports doesnt work.
I tried the UsbInjectall kext but it doesnt work. PLEASE HELP ME OUT to get the USB ports recognized

Don’t use BIOS firware 1603! Convert back to 1503 using EZ Flashback. You might need some CMOS resets in addtion.

USB firware issue is several times mentioned within various recent posts along my x299 threads!

Good luck

Don’t use 1603! Downgrade and use xhc usb kext as soon USB ACPI table works again! Verify XHCI in IOREG. With 1603 it will not be populated at all! That’s why all USB 2.0 and 3.0 ports fail.

Really known issue if one also reads what others post ;)

Long time ago.. actually no lag, jumping or delay with mouse cursor neither on my X299 nor X99 builds.

Anyway.. do you face this issue with cable or BT mouse?

Solution:
1.) Use AGPMEnabler.kext of @apfelnico, being part of my EFI-Folder distributions.
2.) Check/improve BT antenna and BT implementation.

Good luck,

KGP

Right, my Rig did only once run with 1603 and USB ASMedia Ports working. But not for long...

Went back to 1503, which is absolutely stable.

Contacted Asus and asked for a newer Version BIOS with this fixed. Interested about their answer.
 
hi @flymovies, seems you are using ASUS Hyper M.2 x16 card, may i know whether osx can find the raid 0 set by hyper x16?

thanks.

Yes, I am using the card, since I do not get native NVME speeds on the mainboard interfaces. Raid 0 cannot be achieved afaik, as it uses an operating mode OSX cannot understand. So answer is no or respectively: Windows only.
