That's the point of the article--Linux will be the first OS to support USB 3.0.
Nice-looking demo-ware. Got any real drivers or devices? Didn't think so.
I've been developing USB hardware and software for over a decade. Many years I was active in the USB 1.0 roll-out. Motherboard manufacturers were showing motherboards with USB connectors cobbled onto them -- WITH NO CIRCUIT TRACES CONNECTED. Pure show-n-tell.
So unless you can show me a USB 3.0 driver, and a USB 3.0 device, plugged into that motherboard, my opinion is that it is just marketing-ware or an engineering prototype.
