+What:		/sys/bus/usb/devices/.../power/persist
+Date:		May 2007
+KernelVersion:	2.6.23
+Contact:	Alan Stern <[email protected]>
+Description:
+		If CONFIG_USB_PERSIST is set, then each USB device directory
+		will contain a file named power/persist.  The file holds a
+		boolean value (0 or 1) indicating whether or not the
+		"USB-Persist" facility is enabled for the device.  Since the
+		facility is inherently dangerous, it is disabled by default
+		for all devices except hubs.  For more information, see
+		Documentation/usb/persist.txt.

+What:		/sys/bus/usb/devices/.../power/autosuspend
+Date:		March 2007
+KernelVersion:	2.6.21
+Contact:	Alan Stern <[email protected]>
+Description:
+		Each USB device directory will contain a file named
+		power/autosuspend.  This file holds the time (in seconds)
+		the device must be idle before it will be autosuspended.
+		0 means the device will be autosuspended as soon as
+		possible.  Negative values will prevent the device from
+		being autosuspended at all, and writing a negative value
+		will resume the device if it is already suspended.
+
+		The autosuspend delay for newly-created devices is set to
+		the value of the usbcore.autosuspend module parameter.

+Contact:	Sarah Sharp <[email protected]>
+Description:
+		If CONFIG_PM_RUNTIME is enabled then this file
+		is present.  When read, it returns the total time (in msec)
+		that the USB device has been active, i.e. not in a suspended
+		state.  This file is read-only.
+
+		Tools can use this file and the connected_duration file to
+		compute the percentage of time that a device has been active.
+		For example,
+		echo $((100 * `cat active_duration` / `cat connected_duration`))
+		will give an integer percentage.  Note that this does not
+		account for counter wrap.

+Contact:	Sarah Sharp <[email protected]>
+Description:
+		When read, this file returns 1 if the interface driver
+		for this interface supports autosuspend.  It also
+		returns 1 if no driver has claimed this interface, as an
+		unclaimed interface will not stop the device from being
+		autosuspended if all other interface drivers are idle.
+		The file returns 0 if autosuspend support has not been
+		added to the driver.

+		configuration with a value equal to 0. Writing 0 to
