                 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.

+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.
