/*
 *  HID driver for Saitek devices.
 *
 *  PS1000 (USB gamepad):
 *  Fixes the HID report descriptor by removing a non-existent axis and
 *  clearing the constant bit on the input reports for buttons and d-pad.
 *  (This module is based on "hid-ortek".)
 *  Copyright (c) 2012 Andreas Hübner
 *
 *  R.A.T.7, R.A.T.9, M.M.O.7 (USB gaming mice):
 *  Fixes the mode button which cycles through three constantly pressed
 *  buttons. All three press events are mapped to one button and the
 *  missing release event is generated immediately.
