It looks like quite a few manufacturers used the controller (Renesas). I'm trying to remember where I got the driver for my motherboard. I think I got it from Gigabyte. IIRC the installer is buggy to.http://ca.gigabyte.com/products/product-page.aspx?pid=3449&dl=1#driver
link might not work. Gigabyte, motherboard, x58, GA-X58A-UD3R, has a NEC USB 3.0 controller driver. Might work for you.
Try un-zipping the driver but don't use the installer. Uninstall any driver that you have, then use the hardware wizard or Update driver from the device manager. Then point to the unzipped folder and find the .inf file. I know I had to beat the crap out of this driver to get it install in Windows.
