title: Finding information about all serial devices connected through USB in C#
body: <p>My project requires detection of a specific device when it is connected to USB. The only way I can identify this device is by its description/device name, not the com port. What I have found to perform the correct function is using a WMI query and checking the name property:</p>
  
  <pre><code>ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * from WIN32_SerialPort");
              foreach (ManagementObject port in searcher.Get())
              {
                  deviceName = (string)foundPort.GetPropertyValue("Name"); 
                  ...
  </code></pre>
  
  <p>I initially tested this by connecting my phone, and the query returned the phone found on COM3 as expected. Then, I connected another device (a USB to serial converter, which more closely resembles the device I need this project for) and the query simply did not find it. It only finds the phone. This device does, however, show up on port COM4 in Device Manager. To spite me even more, the SerialPort class finds both devices, but it does not provide the information I need to identify the device:</p>
  
  <pre><code>    string[] tempPorts = SerialPort.GetPortNames();
  </code></pre>
  
  <p>I have read numerous threads on SO and elsewhere and cannot find a satisfactory solution. Could someone please clarify why the WIN32_SerialPort query does not find my other device? Is it not considered a win32 serial port for some reason?
  And, could someone please point me in the direction of a solution to this problem?</p>
