Subject: Ejecting/Powering off/ -> Turn off the device lamp.

All,

I have done an extensive search on this issue and cannot find the answer 
to my specific question.  Whereas I understand that an individual device 
on a USB host (on board) cannot be "powered off" nor "ejected" I wonder 
if the device can be sent a command from userspace to turn off it's LED 
indicator lamp.  Most of the devices that I have seen, when the device 
is no longer in use, goes into a blink cycle.

Is there a way to signal the device to stop the cycle and actually power 
off the LED?

Thanks in advance for any help you can give.

Andy Kennedy
