Stallion Port Devices Driver

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.

Laptops and netbooks:: thinkpad t series laptops:: thinkpad t490 type 20n2 20n3contentdetail - Lenovo Support US. Because from what i am reading, changing the com port number in the ini file, will allow you to control what com port gets assigned to the Topaz device in Windows. Are you using the topaz HSB to Com driver? If so this document might be helpful. Steps 4 and 5 explain how to modify the SigPlus.ini file to set the com port that you need it to use.

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.
