Comment(by SimonKagstrom):

 I checked the source code and it looks correct. In
 __enable_data_collection, we do this when enabling the data collection
 with a threshold:

           __reg_write(lis, LIS302DL_REG_FF_WU_CFG_1,
                            LIS302DL_FFWUCFG_XHIE | LIS302DL_FFWUCFG_YHIE |

 So it should be "high" events. I also tested on my freerunner on stable-
 tracking, and for me it appears to work fine (although it's input devices
 3 and 4 here). It's quiet when flat on the table, but as I pick it up,
 data starts flowing.

 I set the threshold to 100.
