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.
