Overview

The hconf driver provides support for generic MS Windows Precision Touchpad configuration collection. It enables the host to configure two different aspects of the device. One allows the host to select input mode, and the other allows the host to be selective in what is reported.

dev.hconf.*.buttons_switch

Enable / disable switch for buttons: 1 = on, 0 = off.
