USB 3.1 is likely on an ASMedia chip so that makes sense. I’m still willing to bet your usb isn’t properly setup to exclude usb2.0 addresses that you’re not using and they’re populating your 15 port limit.
have you tried enabling the OC Quirk ‘XhciPortLimit’ (set it to true/yes)?
My motherrboard only has 9 USB ports on the whole system. So the port limit doesn't exceed. (I also did try hackintool and USB map with injections and ppl enabled with no help.) In addition to the kexts and amls of other people with same board - all of my hardware was correctly written on files (as I did my own as well).
But I did get thing to work today (finally!) by updating to latest firmware 2002 again and setting off legacy USB on BIOS + on every boot the first thing to connect to my XHCI controller being a mass storage device (don't know why ). After that, everything works great.
Luckily somebody has similar problems at discord with their X299.
