Can anybody help me with slipstreaming USB 3.1 drivers into Vista?

As a personal project, I’m trying to triple boot 10, 7 and Vista on a Ryzen system. I’m about ready to admit defeat with Vista, but I was pointed here as a last ditch effort by the lovely folks over at, and figured I might as well ask. I’m getting the typical lack of keyboard and mouse in setup, and vLite isn’t working for some reason (managed to use the wayback machine to access the original host site). I even tried the AMD drivers in the stickied thread, no dice. Is there anything I can do here, or am I just gonna have to throw in the towel?
