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-fin-
     ger 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.

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.

SEE ALSO
     sysmouse(4), usb(4), loader.conf(5), xorg.conf(5) (ports/x11/xorg), moused(8), sysctl(8)
