Note 10:
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.
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 PCs) 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.
Bus powered hubs receive power from a self-powered or root port hub. In this case the maximum
current available from the USB +5 V is 100 mA. The minimum USB +5 V voltage level can be as low
as 4.1 V.
Note 11:
This refers to the total amount of current that can be sourced from the USB +5 V, analog outputs
and digital outputs.
