1、可根据dbch_devicetype（DBT_DEVTYP_DEVICEINTERFACE和DBT_DEVTYP_VOLUME），分别得到PID/VID/SN和盘符号。
2、当USB设备不是存储设备时，只出发一次WM_DEVICECHANGE，devicetype是DBT_DEVTYP_DEVICEINTERFACE
3、当USB设备是存储设备时，会触发两次WM_DEVICECHANGE，一次是DBT_DEVTYP_DEVICEINTERFACE、一次是DBT_DEVTYP_VOLUME
4、插入时，先DBT_DEVTYP_DEVICEINTERFACE后DBT_DEVTYP_VOLUME
5、拔出时，先DBT_DEVTYP_VOLUME后DBT_DEVTYP_DEVICEINTERFACE
6、即使是存储设备，有时也不会触发DBT_DEVTYP_VOLUME，这个问题还没搞清楚。
