Yes, the 0x05 event is a event reflect to g-sensor, but I don't have any
hardware can test it.
Did you see any other value but not just "0x05 0x01 0x00 0x00 0x00 0x00
0x00 0x00" ?
I mean if you invert your table, did you see other return value? The
return data must point to Portrait or Landscape view.
