In X, devices can send two types of events: Core events (as defined  
in the core X Protocol specifications) and X Input Extension events.

X requires you to have exactly one core pointer. The core pointer  
will only send core events.
Any additional devices you specify will send X Input Extension  
events. However, if you need them to send core events as well (which  
is usually the case), you will have to configure them to do so.
