Hokay, so...
I've assembled a new PC which includes an Asrock Z370 PRo4 motherboard and an i5 8600k. My copy of Win7 was specifically prepared for being transferred to a different computer, so I just plugged the system SSD in, no biggie. And yes, Windows did run with no trouble.

Problem is, windows doesn't recognise the USB ports, apparently it lacks the usb 3.0 drivers. The mouse and keyboard work fine in UEFI, but no dice in Windows.
I connected the ssd back to the old PC and tried to install the usb 3.0 drivers but the prompt says my computer doesn't meet the sys requirements (obviously...)
I tried connecting the front panel USB ports to the legacy 2.0 ports on the MB - no dice (WHY?).

Is it possible to manually install drivers for a device that is not currently present in the system? Or will I have to go and buy a usb->Ps/2 adapter?

Worst case scenario here will be a fresh install of Win10, but I'd much much rather not do that right now.
 
Solution
Asrock does not have ANY download files for Win 7. The manufacturer only supports Win 10 on that motherboard. You will probably not find a good solution.
Can you please share what you did to prepare your copy of Win7 to be transferred over to the Z370 motherboard?
