28 | * There are three different types of Synaptics USB devices: Touchpads, | |
29 | * touchsticks (or trackpoints), and touchscreens. Touchpads are well supported | |
30 | * by this driver, touchstick support has not been tested much yet, and | |
31 | * touchscreens have not been tested at all. | |
32 | * | |
33 | * Up to three alternate settings are possible: | |
34 | * setting 0: one int endpoint for relative movement (used by usbhid.ko) | |
35 | * setting 1: one int endpoint for absolute finger position | |
36 | * setting 2 (cPad only): one int endpoint for absolute finger position and | |
37 | * two bulk endpoints for the display (in/out) | |
38 | * This driver uses setting 1. | |
