In some cases, if you are connecting devices which, when combined, are
consuming more power than your computer's USB port can supply, the Mini Hub
will perform an automatic shutdown. This will be indicated by the green LEDs
turning off. A notebook computer's USB port may supply 500 mA of power; but
each port from the Mini Hub is capable of supplying 1100 mA of power to a USB
device. If you've connected one mouse (100 mA) and one keyboard (100 mA), and
then try to connect a third device requiring 400 mA such as a camera, you've just
attempted to use 600 mA of power from a computer's USB port capable of
supplying only 500 mA. In this example, the computer's USB port shuts down
causing an automatic shutdown of the Mini Hub with the green LEDs turning off.
If this happens, follow these steps to reset the Mini Hub:
Disconnect the Mini Hub USB cable from the computer
 
Connect the AC adapter to the Mini Hub as described in the Installation
 
section under self-powered mode.
Reconnect the Mini Hub to the notebook computer.
