So the "eject" command is better than the (p)umount cause it goes 
farther by completely remove the device from the system.
The light being still running is just, on some cases, because the stick 
is still pluged in and by the mean still electrically alimented.
See, there are different sort of Stick (I would like to point out the 
light system). On some of them there is 2 LED of different color (even 
though the key seems to have just one light point) . One for the 
alimentation and the other for signaling the access on the stick. Other 
sticks just have the light of access.


I believe Scott is speaking about the second one. So with his stick, 
having the LED on means something is accessing the Stick.
But Norman' Stick got the alimentation light so it will never turn off.
