Did you get a disk with your MOBO and have you installed it? And if you did then go to their website and download the latest drivers for USB 3.0 and try that.
I've gone on their website, and I can't seem to find a USB 3.0 driver.

First item in the list "Renesas USB3.0 Driver (3.xx)"
I have linked the Windows 7 64-bit driver. What operating system do you have?
Edit: Forum doesn't support spaces in links. Just select the correct operating system when you get to the page. Driver available for Win 7 32 and 64 bit, Vista 32 and 64 bit and XP 32 and 64 bit.
No driver for Windows 8, which either means the driver is included with the operating system or they don't have a certified driver for Windows 8.
