WSP(4) BSD Kernel Interfaces Manual WSP(4) 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.
