Jun 18, 2013 How to determine which COM port represent a USB connection? - posted in Windows 7: I have a device connected to the USB and i want to know the COM port. USB connections do not have com port numbers assigned to them unless its a usb-serial adapter which then it will assign a virtual com port #. Instead they have an address assigned to them. A simple way that I would do it would be if your running windows 7 is to go to devices and printer by clicking start-then click devices and printers.
I have a Windows C# application . The application connects to a RFID card reader over serial port . Though i have given it COM port 3 by default . I land into situations where user's port is not available and his port being used is something different by his windows OS.
My application does give user the ability to change the COM port , but to find which COM port is being used by their operating system , user needs to go to Device Manager and check , which a novice person might not be comfortable with .
Is there a function or a way to find exactly to what port is my RFID card connected to in Windows , so that i can simply display like :
Application Port Set to : COM ....Device Connection Port on OS : COM ....
Also my target framework is 3.5

Hi @user3828453 how about the following and then you can, just use the correct port number which is returned if you still have an empty port than you have to ask the user to go into device manager and update the port via your interface.
