I have a USB device that have been using for years in older Ubuntus to which I can talk via serial port. lsusb shows the device. I am now trying to find in which serial port it is (i.e. /dev/whatever), I have tried with this and it is not showing up, I have also tried with python3 -m serial.tools.list_ports and get no ports found. I already uninstalled brltty as suggested here and restarted the PC. Still the same.

Try the following to make a USB serial device appear in the /dev folder. Open a terminal:
sudo apt remove brltty
This solution is from a previous post: AskUbuntu question 1403705
I found this solution in August and needed to resolved the issue with another computer this December!
