I would like to thank you guys for trying to help me on this problem but I think the problem is this new marvel and usb 3.0 controller (Marvell 88SE9182 chip & Renesas D720200) because on my other Gigabyte mobo I never had problem with usb 3.0. I give up!! I 'm going to Z68 motherboard with corei7 2600K.
Thanks!!
