+/*
+ * linux/include/linux/mouse.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).
