Hub supplies power when computer is shut down


#1

The Plugable USB 3.0 7-port 25-watt hub continues to supply power to my midi controllers (M-Audio 25 and 61 keys) after the host laptop is shut down (all the blue lights go out on the hub though). All my other USB devices on this hub power down though. To power down the midi keyboards, I have to unplug the power adapter to the USB hub.

Is this normal behavior or might the Plugable hub be defective?
