-Description:
-               Each USB device directory will contain a file named
-               power/level.  This file holds a power-level setting for
-               the device, either "on" or "auto".
-
-               "on" means that the device is not allowed to autosuspend,
-               although normal suspends for system sleep will still
-               be honored.  "auto" means the device will autosuspend
-               and autoresume in the usual manner, according to the
-               capabilities of its driver.
-
-               During normal use, devices should be left in the "auto"
-               level.  The "on" level is meant for administrative uses.
-               If you want to suspend a device immediately but leave it
-               free to wake up in response to I/O requests, you should
-               write "0" to power/autosuspend.
-
-               Device not capable of proper suspend and resume should be
-               left in the "on" level.  Although the USB spec requires
-               devices to support suspend/resume, many of them do not.
-               In fact so many don't that by default, the USB core
-               initializes all non-hub devices in the "on" level.  Some
-               drivers may change this setting when they are bound.
