ABSTRACT
This chapter looks at the design of the Plug and Play (PnP) system and how PnP drivers fit into a device stack. A device stack is the means by which several layers of drivers can work together to process user requests. The next chapter looks at how to implement Plug and Play in detail, and describes the Wdm2 example. As well as PnP, Wdm2 supports Power Management, as described in Chapter 10.
