"Self-powered hub" refers to a USB hub with an external power supply. Self-powered hubs allow
Note 7:
a connected USB device to draw up to 500 mA. "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. If your
laptop PC is constrained to the 100 mA maximum, you need to purchase a self-powered hub.
This refers to the total amount of current that can be sourced from the USB +5 V and digital
