/*

 * There are three different types of Synaptics USB devices: Touchpads,

 * touchsticks (or trackpoints), and touchscreens. Touchpads are well supported

 * by this driver, touchstick support has not been tested much yet, and

 * touchscreens have not been tested at all.

 *

 * Up to three alternate settings are possible:

 *  setting 0: one int endpoint for relative movement (used by usbhid.ko)

 *  setting 1: one int endpoint for absolute finger position

 *  setting 2 (cPad only): one int endpoint for absolute finger position and

 *         two bulk endpoints for the display (in/out)

 * This driver uses setting 1.
