问题描述

当系统（平板电脑）已添加到系统或从系统中删除时，系统会广播DBT_DEVNODES_CHANGED设备事件。要广播此设备事件，系统将使用WM_DEVICECHANGE消息，其中wParam设置为DBT_DEVNODES_CHANGED且lParam设置为零。如何知道有关在系统中添加或删除哪个设备的其他信息。

The system broadcasts the DBT_DEVNODES_CHANGED device event when a device(a tablet PC) has been added to or removed from the system.To broadcast this device event, the system uses the WM_DEVICECHANGE message with wParam set to DBT_DEVNODES_CHANGED and lParam set to zero.How can I know additional information about which device has been added to or removed from the system.

推荐答案

您可以使用应提供Devicename，ID的WMI。 ..



使用SELECT * FROM Win32_USBControllerDevice查看WMI，它应该将您的设备放在集合中，基本上所有参数窗口都知道它。

You can work with the WMI it should provide Devicename, ID ...

Look in the WMI with "SELECT * FROM Win32_USBControllerDevice" it should have your device in the collection and basicly all parameter windows knows about it.
