+         HID Sensor hub specification allows definition of some custom and
+         generic sensors. Unlike other HID sensors, they can't be exported
+         via Linux IIO because of custom fields. This is up to the manufacturer
+         to decide how to interpret these special sensor ids and process in
+         the user space. Currently some manufacturers are using these ids for
+         sensor calibration and debugging other sensors. Manufacturers
+         should't use these special custom sensor ids to export any of the
+         standard sensors.
+         Select this config option for custom/generic sensor support.
