.Sh NAME
.Nm wsp
.Nd Wellspring touchpad driver
.Sh SYNOPSIS
To compile this driver into the kernel, place the following lines into
your kernel configuration file:
.Bd -ragged -offset indent
.Cd "device wsp"
.Cd "device usb"
.Ed
.Pp
Alternatively, to load the driver as a module at boot time,
place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
wsp_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver provides support for the Apple Internal Trackpad
device found in many Apple laptops.
.Pp
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.
.Pp
.Nm
supports dynamic reconfiguration using
.Xr sysctl 8
through nodes under
.Nm hw.usb.wsp .
Pointer sensitivity can be controlled using the sysctl tunable
.Nm hw.usb.wsp.scale_factor .
Tap to left-click can be controlled using the sysctl tunable
.Nm hw.usb.wsp.enable_single_tap_clicks ,
set to 0 to disable single tap clicks or 1 to enable them (default).
.Sh FILES
.Nm
creates a blocking pseudo-device file,
.Pa /dev/wsp0 ,
which presents the mouse as a
.Em sysmouse
or
.Em mousesystems
type device--see
.Xr moused 8
for an explanation of these mouse
types.
