获取设备的PID与VID的方法
下面小编来为大家讲讲获取设备的PID与VID的方法，方法很简单，看了便知：
获取方法：
1.鼠标右键点击&计算机&（win xp中是&我的电脑&），选择&管理&（或设备管理器）
2.连接手机设备，在设备的一栏点击鼠标右键，选择属性
3.选择详细信息，选中任意一项右键，并选择复制。粘贴至文本文档或其他便于记录的地方即可
注意：win xp中不能直接复制该项，此时请对照找到的PID和VID，手动输出
小编点评：以上就是获取设备的PID与VID的方法，希望可以帮助大家顺利解决问题！

See also the Multifunction class.MonitorClass = MonitorClassGuid = {4d36e96e-e325-11ce-bfc1-0}This class includes display monitors. An INF for a device of this class installs no device driver(s), but rather specifies the features of a particular monitor to be stored in the registry for use by drivers of video adapters.
