NAME

     wsp — Wellspring touchpad driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines into your kernel configuration file:

           device wsp
           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).

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.
