Controling USB port's power using Assembly program -


i write program (assembly), allows me control power supply usb port motor. i've been told it's possible, know how can done, i'm not asking write code, want know method.

i think easier way of doing use following devices , via hardware. these provide better programming interface little hardware knowledge needed. avoid trying usb host controller has have custom code written usb power method working , if you're lucky, won't fry controller.
