c# - 在 Windows 和 NET 中获取有关连接的 USB 设备的所有可用信息

Question

我已经实现了 SO question 的解决方案在我的代码中，但我正在从连接的 USB 设备中寻找更多信息。

我注意到在我的设备管理器中提供了相当多的信息。

我特别想了解设备的制造商。

我不确定如何确定哪些其他属性可以从 SO question 中看到的 GetPropertyValue 方法使用.上次尝试了一些关键字，但都报错，所以我假设是不可用的属性。

除了 DeviceID、PnpDeviceID 和 Description 之外，我知道如何获取更多信息吗？

编辑:对于任何想知道这里是属性的完整列表和我为它们获得的值的人。据我所知，没有任何设备提供的内容多于或少于此处所见(可能是转换为字符串？)。

               Availability: 
                    Caption: USB Root Hub
                  ClassCode: 
     ConfigManagerErrorCode: 0
    ConfigManagerUserConfig: False
          CreationClassName: Win32_USBHub
   CurrentAlternateSettings: 
         CurrentConfigValue: 
                Description: USB Root Hub
                   DeviceID: USB\ROOT_HUB20\########
               ErrorCleared: 
           ErrorDescription: 
               GangSwitched: 
                InstallDate: 
              LastErrorCode: 
                       Name: USB Root Hub
            NumberOfConfigs: 
              NumberOfPorts: 
                PNPDeviceID: USB\ROOT_HUB20\4&\########&0
PowerManagementCapabilities: 
   PowerManagementSupported: 
               ProtocolCode: 
                     Status: OK
                 StatusInfo: 
               SubclassCode: 
    SystemCreationClassName: Win32_ComputerSystem
                 SystemName: ASystemName
                 USBVersion: 

并从链接的 SO 答案中编辑代码，但具有所有属性。
