How to list all attached USB devices in Visual C++
提问by vinzenzweber
In Short:I need to detect hotplug events of my USB CDC device by PID/VID and get the corresponding virtual COM port which was created by Windows in Visual C++ and in the end create a dll.
简而言之：我需要通过 PID/VID 检测我的 USB CDC 设备的热插拔事件，并获取由 Windows 在 Visual C++ 中创建的相应虚拟 COM 端口，最后创建一个 dll。
I have a USB CDC device which I need to be notified of when connected/disconnected on Windows. My approach is to use RegisterDeviceNotificationand an "invisible" Window to receive WM_DEVICECHANGEnotifications. This part is working so far.
我有一个 USB CDC 设备，在 Windows 上连接/断开连接时需要通知我。我的方法是使用RegisterDeviceNotification“隐形”窗口来接收WM_DEVICECHANGE通知。到目前为止，这部分正在工作。
Now as far as I found out I need to get the list of USB devices that is plugged, iterate over it and filter out the devices with my PID/VID? I assume that I am then able to get more informations about the device including the COM port?
现在据我所知，我需要获取插入的 USB 设备列表，对其进行迭代并用我的 PID/VID 过滤掉设备？我假设我然后能够获得有关设备的更多信息，包括 COM 端口？
Is the only way to achieve my goal to use SetupDicalls in setupapi.h? Is using WDK / DDK the only way to achieve my goal?
是实现我使用SetupDi调用目标的唯一方法setupapi.h吗？使用 WDK / DDK 是实现我的目标的唯一方法吗？
As soon as that is working I open-source it on http://github.com/vinzenzweber/USBEventHandler. The Mac version is available already!
一旦它起作用，我就在http://github.com/vinzenzweber/USBEventHandler上将其开源。Mac 版本已经可用！

After digging through tons of useless documentation at msdn and some debugging I found the missing link: SetupDi calls in setupapi.h: More infos as well as source code for Mac and Windows can be found in my USBEventHandler project at github.comwith sources for Mac and Windows.
在 msdn 上挖掘了大量无用的文档并进行了一些调试后，我找到了缺失的链接： setupapi.h 中的 SetupDi 调用：更多信息以及 Mac 和 Windows 的源代码可以在 github.com 的 USBEventHandler 项目中找到，其中包含以下源代码Mac 和 Windows。
