+What:		/sys/bus/usb/devices/.../power/level
+Date:		March 2007
+KernelVersion:	2.6.21
+Contact:	Alan Stern <[email protected]>
+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.
+
+		This file is deprecated and will be removed after 2010.
+		Use the power/control file instead; it does exactly the
+		same thing.
