USB3 not working, even with port map, on otherwise perfect Big Sur Clean install on OC

I performed a clean install (and post install time machine backup) of Big Sur 11.5.2 with OpenCore on a machine I had previously running with Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave and Clover. Everything seems to work perfectly apart from the USB3 ports which seem to not be working/detected with any USB device, but do show up in hackintool and system report. The devices and ports work under Windows and my old Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave install.

I used a (now slightly modified) EFI specifically designed for my board by a maintainer...
