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.
