Via generic USB ports on the motherboard. I am running windows 7 using a i7 3.5 ghz prc , Asus Maximus vii hero 16 g ram and 2tb hd. I’m using a generic gaming keyboard and a g700 mouse. The USB ports are working because the mouse led light that show charging are working and when I reboot the pc the lights on the keyboard are on but once windows boots neither work
