- /*
- * 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).
