    15 <p>A device driver is a program that controls a particular type of device
       
    16 that is attached to a base port. Writing a device driver requires an in-depth
       
    17 understanding of how the hardware and the software of a given platform function.
       
    18 The Device Driver writing guide tells you what you need and how to create
       
    19 a device driver.</p>
