        注意获取窗口句柄一定要写在窗口loaded事件里，才能获取到窗口句柄，否则为空
        hwndSource = PresentationSource.FromVisual(this) as HwndSource;//窗口过程
        if (hwndSource != null)
            hwndSource.AddHook(new HwndSourceHook(_godeComeraBuilder.DeveiceChanged));  //挂钩  _godeComeraBuilder.DeveiceChanged 要挂在的方法，USB拔插时触发改方法
    }

   public IntPtr DeveiceChanged(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled){
      return IntPtr.Zero;
