USB 3.0 not working a75m-hvs

Hello, I just installed my MB and the 4 USB 3.0 ports on the back are not working. It's an a75m-hvs. I was under the impression that those ports are backwards compatible so. But if I plug in my mouse or keyboard they do not work. I installed all the drivers that came with the cd and I have search on asrock's site for additional drivers with no luck. Everything in the bios looks good too. Any ideas?

    U need to install the drivers for the USB3, they don't come included in the OS yet. If u try the USB2, it should work just fine.

    The USB 2.0 devices dont work either on those 4 3.0 ports..... I installed the AMD All-in-one driver that came with the MB but i'll try downloading the new one from the site. I'm sure it has to be a driver issue or when I was having problems loading the OS i was messing with the bios a little. Maybe i should just reset the bios to default or see if there is an update for the bios as well.
  3. The new drivers from the site did it! thanks!
