USB3 ports don't work at all - ASUS p8z77-v board

[FabCa]

Hi,

Half of my ports, all the USB3 don't work at all which is a bummer..!
I have no clue on how to fix this.
Anyone does? Thx

I tried tweaks i found here and there but not luck.

The USB option in LION Multibeast made the ports working with USB3 devices only and gave me sleep troubles + I got troubles unmounting devices on all ports...

The 10.8.3 update didn't help eather...

Anyone who has a hint?
Thanks
