You should end up seeing something like this:Īs I mentioned above, with the initial search terms I was finding online (Serial, VCP) I was unable to locate the culprit. The list started from this Stackoverflow reply.

I’ll cover these here (including the one that worked for me), but I’ll also help you try to find other strings you could search for below. You should see a window that looks like this:Īt first, there are a few different strings you can search for. If you are on a 64-bit system (most likely with newer systems) run procexp64.Otherwise you may not be able to have insight in to all of the processes running on the system. IMPORTANT: Make sure you run Process Explorer in the next step AS ADMINISTRATOR (via the right-click menu).

That said, I would like to explain how to figure out what process is using the COM port because this may not be the culprit for you. In my case I will say that the culprit was NZXT CAM a program which controls my NZXT liquid cooling setup. (Let alone, if the pertinent messages came up right after the device rebooted after a programming session.) If I programmed the device I would then get the ‘port busy’ message afterwards.Īnd, having to reboot after every single programming run just to see serial output was just not going to happen. The only time I could access the device was after a fresh reboot. No matter what I tried, over the course of multiple debug sessions I couldn’t it out. (Port Busy) (Your COM port number may vary.) Something like: Error opening serial port 'COM14'.

The error messages typically indicated that the COM port was busy. I was running in to a number of issues with the Arduino IDE not being able to connect to my Arduino’s serial port.
