Hi Guys!
My name is Matteo, this is my first post on this awesome forum.
I've just bought the ROG notebook G75VX-CV006H.
Two days ago I've installed a new SSD Hard Disk, so I've formatted and reinstalled Windows 8 64bit.
After that my Usb 3.0 disk has stopped to work faster then 2.0, now 2.0 and 3.0 disks goes at the same speed.
I've installed all the most updated driver and the latest version of bios, but I haven't see any improvements.
Any advice?

Thanks

Solved!

I've just to enable XHCI Pre-Boot Mode into the Bios settings.
(Advanced-> USB Configuration -> XHCI Pre-Boot Mode -> "Enable")
