如何确定键盘在DirectInput断开连接 [英] how to determine keyboard disconnected in DirectInput

问题描述

我使用EnumDevices（...，DIEDFL_ATTACHEDONLY）监控HID连接。当我断开游戏控制器，它不再显示在回调。然而，当我断开键盘，它仍然显示在EnumDevices。

I am monitoring HID connections using EnumDevices(..., DIEDFL_ATTACHEDONLY). When I disconnect a game controller it no longer shows up in the callback. However, when I disconnect the keyboard, it still shows up in EnumDevices.

我已经看过API，但我没有看到其他地方查询，如果一个设备已连接。

I've looked through the API, but I don't see where else to query if a device is connected.
