How can I detect a USB disconnect event? (Windows, .NET C# application)
提问by Jon
Currently how I do this is I poll for a masked list of USB devices (masked specifically for the device I'm working with) and if it's there, I continue, if not then I notify the user that the device is not connected. The method for getting a list of USB devices is provided for me through a USB peripheral controller chip manufacturer's .NET library.
目前我的做法是轮询 USB 设备的屏蔽列表（专门为我正在使用的设备屏蔽），如果它在那里，我继续，如果没有，我会通知用户该设备未连接。通过USB外围控制器芯片制造商的.NET库为我提供了获取USB设备列表的方法。
Is there an event somewhere for a USB device disconnect?
某处是否有 USB 设备断开连接的事件？
