Yes, you right. I did not understand purpose of field 'direction'
and this one does not directly used in hid-lgff.c. I think,
theoretically (in future?) this field may cause problems with
difficult joysticks with more than 2 independent axises with feedback
(for example, X (left/right), Y (up/down) and throttle
(forward/backward)).
   Thanks.
