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.
