Root Port Hubs reside in the PC's USB Host Controller. The USB port(s) on your PC are
root port hubs. All externally powered root port hubs (desktop PC's) provide up to 500 mA
of current for a USB device. Battery-powered root port hubs provide 100 mA or 500 mA,
depending upon the manufacturer. A laptop PC that is not connected to an external power
adapter is an example of a battery-powered root port hub.
