NAME

wsp – Wellspring touchpad driver

CONTENTS

SYNOPSIS

To compile this driver into the kernel, place the following lines into your kernel configuration file: device wsp device hid device usb

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): 

wsp_load="YES"

DESCRIPTION

The wsp driver provides support for the Apple Internal Trackpad device found in many Apple laptops.

The driver simulates a three-button mouse using multi-finger tap detection. A single-finger press generates a left button click. A two-finger tap maps to the right button; whereas a three-finger tap gets treated as a middle button click.

wsp supports dynamic reconfiguration using sysctl(8) through nodes under hw.usb.wsp. Pointer sensitivity can be controlled using the sysctl tunable hw.usb.wsp.scale_factor. Tap to left-click can be controlled using the sysctl tunable hw.usb.wsp.enable_single_tap_clicks, set to 0 to disable single tap clicks or 1 to enable them (default). Z-Axis sensitivity can be controlled using the sysctl tunable hw.usb.wsp.z_factor. Z-Axis inversion can be controlled using the sysctl tunable hw.usb.wsp.z_invert, set to 0 to disable (default) or 1 to enable inversion.

FILES

wsp creates a blocking pseudo-device file, /dev/wsp0, which presents the mouse as a sysmouse or mousesystems type device--see moused(8) for an explanation of these mouse types.
