I was talking about intels ability to add usb3 and not addon cards, but I didn't realise the practical problems of using usb3 addon cards or devices developed with the already released usb3 development kit and chips on intel boards. I guess the addon card makers dropped a clanger and this will be rectified. Do you know if they just run at a lower speed on some boards?
