To  enable  an	 extended  device, you	must   add   en  entry	in the XF86Con-
fig file.   Consult   to  the XF86Config  man pages to see the details.

3.2  Clients

xsetpointer is used to	change the device controlling the core pointer and to
list available extended devices.

xsetmode is used to change the mode (absolute or relative) of an extended
device. The device  has to  support relative and  absolute modes and the device
must not control the core pointer.
