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.

The Pepperl+Fuchs Comtrol DeviceMaster Serial Hub 16-Port network enables up to 16 serial communications devices. When used with the included NS-Link™ driver software and a host PC, the DeviceMaster Serial Hub enables placement of COM or TTY ports anywhere on an Ethernet network or across the Internet. 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. Our Clackamas Oregon model RR club has two Dell Optiplex 755 laptops purchased used from a recycle store. The one that communicates with our layout NCE power module through the serial port has stopped communicating and Windows Vista device manager reports the PCI serial port driver is missing and also the PCI simple communications controller and PCI bus controller drivers. Provide an INF file that specifies the Ports device setup class and the Serial function driver as the service for the port. To configure a serial port as COM port, comply with the requirements that are defined in Configuration of COM Ports.
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.
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.

How to find the VID and PID numbers
To find the vid (Vendor ID) and PID (Product ID) of a serial USB device first you need to attach the device with your PC. Now you need to follow the below steps to get the vid and PID.
1. Go to Control Panel > Device Manager > Ports.

2. Select the desire com port and double click on it or right-click and select Properties.
3. Go to the Details tab and select Hardware ID to view its PID and VID.
