Hey.
I have the normal z390 Taichi board and after initial uefi settings of setting a boot order and I go off to install windows my usb devices are not active until very late in the boot up in windows which doesn't allow me to get into uefi or use the keyboard to do advanced windows boot up options.
I have moved my keyboard to top let usb as you look at the back panel but it hasn't fixed it.
When I reset the cmos then the keyboard and other usb devices are active on startup.
Using the out of the box bios
