在需要响应此消息的窗口Init函数中添加以下代码即可：
1 DEV_BROADCAST_DEVICEINTERFACE Filter; 2 ZeroMemory(&Filter, sizeof(Filter)); 3 Filter.dbcc_size = sizeof(Filter); 4 Filter.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE; 5 GUID WceusbshGUID = { 0x25dbce51, 0x6c8f, 0x4a72, 0x8a,0x6d,0xb5,0x4c,0x2b,0x4f,0xc8,0x35 }; 7 Filter.dbcc_classguid = WceusbshGUID; 8 //DEVICE_NOTIFY_ALL_INTERFACE_CLASSES //关注所有设备事件 9 HDEVNOTIFY m_hDeviceNotify = RegisterDeviceNotification(this->m_hWnd, &Filter, 0x00000004);
