+Here I will gather all info I can find out about the different force effects and
+their USB commands. All values seem to be little-endian.
+Also, general note, it seems like some effects are affected by the direction of
+the force, denoted by ***
+
+As far as I can tell, fade_level and attack_level values are calculated by
+mapping the u16 into s16 and taking the absolute value, and after that
+multiplying by the direction.
+
+All values are examples of actual commands that I captured on the USB interface,
