#ifndef _LINUX_BUSMOUSE_H
#define _LINUX_BUSMOUSE_H
/*
* linux/include/linux/busmouse.h: header file for Logitech Bus Mouse driver
* by James Banks
*
* based on information gleamed from various mouse drivers on the net
*
* Heavily modified by David giller (rafetmad@oxy.edu)
*
* Minor modifications for Linux 0.96c-pl1 by Nathan Laredo
* gt7080a@prism.gatech.edu (13JUL92)
*
* Microsoft BusMouse support by Teemu Rantanen (tvr@cs.hut.fi) (02AUG92)
*
* Microsoft Bus Mouse support modified by Derrick Cole (cole@concert.net)
* 8/28/92
*
* Microsoft Bus Mouse support folded into 0.97pl4 code
* by Peter Cervasio (pete%q106fm.uucp@wupost.wustl.edu) (08SEP92)
* Changes: Logitech and Microsoft support in the same kernel.
* Defined new constants in busmouse.h for MS mice.
* Added int mse_busmouse_type to distinguish busmouse types
* Added a couple of new functions to handle differences in using
* MS vs. Logitech (where the int variable wasn't appropriate).
