So I just reinstalled windows 8 on my machine, and I tried loading up youtube to make sure everything was working properly. However, I found that when I play a video, any device connected to my usb 3 ports stops sending data, but still receives power (lights on my keyboard, for instance). Anything plugged into my front usb 2 ports works flawlessly though, so I am wondering what the cause may be. It is probably a mobo thing, and I've heard something about xhci and ehci hand off, but I have no clue what those mean to me. I currently have both enabled in my BiOS, if it matters. Thanks!
