ASRock and ECS first with two USB 3.0 host controllers
 

ONE FLAW WITH USB 3.0 is that you're stuck with only a pair of ports around the back on your motherboard, but it seems like the motherboard manufacturers are getting ready to solve that problem for you. As we reported a couple of days ago, ASRock and ECS are using an internal pin-header, but both of the boards in question also feature two USB 3.0 host controllers.

ASRock’s board is the upcoming P55 Extreme3 which comes with the front mounted USB 3.0 accessory we showed you in the previous story. However, having only a pair of USB 3.0 ports around the front might not suit everyone’s needs, so in addition to the Renesas controller to which the pin-header goes, ASRock kitted out the board with a Fresco Logic controller as well.
