Question

我已在我的代码中实现了SO question的解决方案，但我正在寻找连接USB设备的更多信息。

我注意到在我的设备管理器中提供了更多信息。

我特别想知道这些设备的制造商。

我不确定如何根据SO question中的GetPropertyValue方法用法确定可用的其他属性。我在最后尝试过一些关键字，但它们都报告错误，所以我认为这些不是可用的属性。

我知道如何获取仅有DeviceID，PnpDeviceID和Description的更多信息？

编辑：对于想知道这里的人来说，我会得到完整的属性列表和值。没有任何设备提供的内容比我所知道的更多或更少（可能是演员到字符串？）。

               Availability: 
                    Caption: USB Root Hub

            NumberOfConfigs: 
              NumberOfPorts: 
                PNPDeviceID: USB\ROOT_HUB20\4&\########&0
