代码说明：

Two categories of devices don’t fit neatly into the PnP framework I described in Chapter 6. These categories are controller devices, which manage a collection of child devices, and multifunction devices, which have several functions on one card. These kinds of devices are similar in that their correct management entails the creation of multiple device objects with independent I/O resources.-Two categories of devices don’t fit neatly into the PnP framework I described in Chapter 6.
