+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.
