.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 hid"
|
|
.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).
|
|
Z-Axis sensitivity can be controlled using the sysctl tunable
|
|
.Nm hw.usb.wsp.z_factor .
|
|
Z-Axis inversion can be controlled using the sysctl tunable
|
|
.Nm hw.usb.wsp.z_invert ,
|
|
set to 0 to disable (default) or 1 to enable inversion.
|
|
.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.
