wsp
— Wellspring
touchpad driver
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"
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).
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.
