Integration of power control FETs into "root hub" is nonsense: power electronics requires vastly different technology and node features to carry hundreds of mAmps, and deep submicron digital technology can't afford mixing. The power control was always implemented in industry as stand-alone high-side switches. This post is mostly misleading. -1. | |

Forget plug-and-play your USB thumb drive! Install drivers and boot with device connected and just maybe it would work. Good old days! | |
