You have to be careful with authorization with serial ports in Linux OS. If you need to authorize a serial port, just type in terminal:
sudo chmod a+rw /dev/ttyUSB0
Be caregul, because if you disconnect and connect the usb again, the port can be /dev/ttyUSB1. And an error could occur when uploading the code.
Besides that, in your OS the serial port could be /deb/ttyACM0 or /deb/ttyACM1 (if the situation above happens).
If the plataform.io isn't showing any ttyUSB or ttyACM ports on ubuntu it probably is related to BRLTTY modules, then we gonna have to remove it. Don't worry this module is related this module is for acessibility related to braile display onto ubuntu.
To start it you gotta list all the devices, just to check if it's working
ls /dev/ttyUSB* #or ls /dev/ttyACM*
if the port isn't showing there, the system hasn't loaded the board, then it probably is the module, to remove it:
sudo apt-get remove --auto-remove brltty
Unplug and replug your board, type again in Terminal
ls /dev/ttyUSB* #or ls /dev/ttyACM*
it probably fixed it for you, but if it hasn't fixed try the link below.
