问题描述
限时送ChatGPT账号..查询适用于 Win32_USBHub
SELECT * FROM Win32_USBHub WHERE DeviceID = '{0}'
这是代码上下文,
// Check if USB device is plugged in
string deviceQuery = String.Format("SELECT * FROM Win32_USBHub WHERE DeviceID = '{0}'", deviceID);
using (var searcher = new System.Management.ManagementObjectSearcher(deviceQuery))
if (searcher.Get().Count == 0)
MessageBox.Show(@"Device not detected");
但是,当设备未在通用串行总线控制器"中列出时,从 Win32_USBHub
查询不会返回我正在寻找的连接设备.
However when a device is not listed inside 'Universal Serial Bus controllers', querying from Win32_USBHub
does not return the connected device I'm looking for.
是否有另一个表"可以从 Win32_USBHub
外部查询,其中包含我正在寻找的Cardio Perfect PRO-Link USB"设备?或者这会是一个自定义表"?
Is there another 'table' to query outside from Win32_USBHub
which would contain device I'm looking for 'Cardio Perfect PRO-Link USB'? Or would this be a 'custom table'?
推荐答案
SELECT * FROM Win32_PnPEntity WHERE DeviceID = '{0}'
我想我搜索的时间不够长,这里有一个链接,其中包含很多非常好的示例...http://msdn.microsoft/en-us/library/aa394587%28v=vs.85%29.aspx
I guess I didn't search long enough, here's a link which contains a lot of really good examples... http://msdn.microsoft/en-us/library/aa394587%28v=vs.85%29.aspx
我正在寻找的表格"是 Win32_PnPEntity
它列出了我连接的所有 155 台设备.
The 'table' I was looking for is Win32_PnPEntity
it listed all 155 devices I'm connected to.
