-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.
