1408 ** The following lines take care of the Logitech MouseMan protocols.
1410 ** NOTE: There are different versions of both MouseMan and TrackMan!
1411 ** Hence I add another protocol P_LOGIMAN, which the user can
1412 ** specify as MouseMan in his XF86Config file. This entry was
1413 ** formerly handled as a special case of P_MS. However, people
1414 ** who don't have the middle button problem, can still specify
1415 ** Microsoft and use P_MS.
1417 ** By default, these mice should use a 3 byte Microsoft protocol
1418 ** plus a 4th byte for the middle button. However, the mouse might
1419 ** have switched to a different protocol before we use it, so I send
1420 ** the proper sequence just in case.
1422 ** NOTE: - all commands to (at least the European) MouseMan have to
1423 ** be sent at 1200 Baud.

1744 * We have already processed the standard packet with the movement

1746 * of the left and right buttons and the updated middle button.
1750 * Even worse, different MouseMen and TrackMen differ in the 4th
