		What: /sys/bus/usb/devices/.../power/persist
		Date: May 2007
		KernelVersion: 2.6.23
		Contact: Alan Stern <stern@rowland.harvard.edu>
		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 <stern@rowland.harvard.edu>
		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.

		What: /sys/bus/usb/device/.../power/connected_duration
		Date: January 2008
		KernelVersion: 2.6.25
		Contact: Sarah Sharp <sarah.a.sharp@intel.com>
		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 connected to the machine. This
		file is read-only.

		What: /sys/bus/usb/device/.../power/active_duration
		Date: January 2008
		KernelVersion: 2.6.25
		Contact: Sarah Sharp <sarah.a.sharp@intel.com>
		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.

		Date: January 2008
		KernelVersion: 2.6.27
		Contact: Sarah Sharp <sarah.a.sharp@intel.com>
		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.

		device will morph into another mode when it is reset.

		KernelVersion: since at least 2.6.18
		Description:
		bConfigurationValue of the active configuration for the

		active configuration (unconfigure the device). Writing
		another value will change the active configuration.

		Note that some devices, in violation of the USB spec, have a
		configuration with a value equal to 0. Writing 0 to
		bConfigurationValue for these devices will install that
		configuration, rather then unconfigure the device.

		Writing -1 will always unconfigure the device.

		Description:
		Binary file containing cached descriptors of the device. The

		descriptors for each configuration of the device.
		Note that the wTotalLength of the config descriptors can not
		be trusted, as the device may have a smaller config descriptor
		than it advertises. The bLength field of each (sub) descriptor
		can be trusted, and can be used to seek forward one (sub)
		descriptor at a time until the next config descriptor is found.
		All descriptors read from this file are in bus-endian format
