wsmouse module is a component of the
  wscons(9) framework to provide
  machine-independent mouse support. Most of the support is provided by the
  wsmouse(4) device driver, which
  must be a child of the hardware device driver.

    The enable member defines the function to be called to enable monitoring pointer movements and passing these events to wscons. The disable member defines the function to disable movement events. The ioctl member defines the function to be called to perform mouse-specific ioctl calls.
There is a void * cookie provided by the mouse driver associated with these functions, which is passed to them when they are invoked.

The wscons framework calls back into the hardware driver by
    invoking the functions that are specified in the accessops
    structure. The enable() and
    disable() functions are relatively simple and
    self-explanatory. The ioctl() function is called by
    the wscons interface to perform mouse-specific ioctl operations (see
    ioctl(2)). The argument
    cmd to the ioctl() function
    specifies the specific command to perform using the data
    data. Valid commands are listed in
    sys/dev/wscons/wsconsio.h.
wsmouse
  module itself is implement within the file
  sys/dev/wscons/wsmouse.c.
  ioctl(2) operations are listed in
  sys/dev/wscons/wsconsio.h.
