【问题描述】:
我已经在我的代码中实现了SO question 的解决方案,但我正在从连接的 USB 设备中寻找更多信息。
我对了解这些设备的制造商特别感兴趣。
我不确定如何从SO question 中看到的GetPropertyValue 方法使用中确定哪些其他属性可用。我在最后尝试了一些关键字,但它们都报告错误,所以我假设它们不是可用的属性。
知道如何获取更多信息,而不仅仅是DeviceID、PnpDeviceID 和Description?
编辑:对于任何想知道这里的人来说,这里是属性的完整列表以及我为它们获得的值。据我所知(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 答案中编辑了代码,但具有所有属性。
