+Description:

+		control whether the time taken by devices to suspend and
+		resume is printed.  These prints are useful for hunting down
+		devices that take too long to suspend or resume.

+		disables it.  The default value is "0".  Reading from this file

 Device low-power states aren't standard.  One device might only handle
