I'm trying to install Win 8 via the Sata DVD drive with a standard USB keyboard and mouse in the USB 2.0 ports. While I am in BIOS, both function properly, as soon as I exit BIOS and get past the "Press any key to boot from CD/DVD" the keyboard and mouse shut off when it gets to the Windows 8 Setup screen.
I have tried unplugging the KB & M while on that screen, plug them to another port, tried it another keyboard and mouse. It's like the USB controller dies post-BIOS. I even went as far as plugging in my SSD from my other PC and Win10 boots up, but something, KB and M do not work.
Any suggestions?
