USB 3.0 "This Device Can Perform Faster"

Hi,

Got a little 'nuisance value' problem that I can't seem to resolve.

I have an Intel DH67VR main board (with i5 2500 Sandybridge CPU, Win7 64Bit Pro SP1)

When I plug in a USB 3.0 device, I get a pop up message: "This Device Can Perform Faster if you plug it into a USB 3.0 port"

Except it is a USB 3.0 device, in either of the 2 USB 3.0 ports at the back. I still get the message, and the memory stick and portable drive do work at USB 2.0 speed. I've tried updating the Renesas drivers, chipset drivers and BIOS. USB 3.0 is enabled in the BIOS setup.

I've tried both devices on my other ASUS Z68 board, no problem.

Any thoughts?
