In my one project, I need to create an application to upgrade the firmware of the device. Here comport is using for the communication. We cannot fix the COM ID of the USB device in the application because the device could be enumerated with different com id on a different machine as per the availability.

So the solution is that displays the list of all known com ports and users select the correct com port. But it is not a good idea to show all com port, I want that application to identify the com id itself.

Calls IoReportDetectedDevice to report the device to the Plug and Play manager. Sets the LegacyDiscovered entry value for the port to 0x00000001, which indicates that the port has been reported. Copies some of the entry values under the COM port subkey to the Plug and Play device key for the physical device object (PDO) that is returned.

Every USB device has a unique hardware id (the combination of VID and PID), so to accomplish the above task my approach is to get COM PORT of USB Serial Device on the basis of VID/PID. The registry of the windows kept the information of the device, so simple logic here to open the windows registry and get the com id.
