It's the feature of hardware controller, of couse, but now it can work only with MS drivers. The reason is the same as overclocking of low speed devices now not worked with Windows 7 + USB 3.0 controllers - i can't RE all OEM drivers in the world
And yes, direct host controller (outside the driver) programming is possible - but this task is _huge_.
