cmd.exe - Removing Com ports in Windows 7 using cmd

I have been trying to find a way to make a script to uninstall specific COM-ports from Windows 7 that are no longer used.

Background:

I'm using NI Teststand to test a productio test of an USB-serial device. This test will change the FTDI config, so each device tested will use two COM-ports. It doens't take long time until there are hundreds of COM-ports present in the system.

What I have tried:

I found this suggestion, but it doesn't seem to work. I can see all the devices when i use:

devcon findall =ports

But from what I have gathered it is only possible to remove active devices using:

devcon remove 

Question:

How can I remove a large number of COM-ports from CMD?

Thanks in advance

I had a similiar issue to remove unused COM-Ports. I am using "COM Name Arbiter Setter" from http://www.uwe-sieber.de/misc_tools_e.html
