Note 3:
Self-Powered Hub refers to a USB hub with an external power supply. Self-powered hubs allow a
connected USB device to draw up to 500 mA. This device may not be used with bus-powered hubs due
to the power supply requirements.
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.
