Hi,

I have an Alienware m17x R4 on Unlocked A10 Bios and I would like to disable the USB 3.0 so Mac OS X Mountain Lion see my USB ports as a normal 2.0 port because right now USB 3.0 isn't supported and I can't plug anything..and it looks like Bluetooth is running on USB Bus so it doesn't work either

Thanks

Edit : xHCI is USB 3.0 and EHCI for 2.0
