If the PORT Menu Is Disabled On Arduino IDE

Not sure if it’s valid for other Linux distributions, but if you’re an Ubuntu 22.04 user, not able to access your board and the PORT menu is disabled, follow the steps below:

• Open your terminal.
• First, make sure the current user is a member ofdialout group.

$ groups $USER

if you can’t see dialout group on the list right after the command, please run the following command:

$ sudo adduser $USER dialout

If it still does not work…

• Take the USB cable from the board out and plug it in back.
• Run sudo dmesg command.

If you see such a line as input: BRLTTY 6.4 Linux Screen Driver Keyboard , this means that the operating system may not have recognized the board.

• Uninstall brlitty package.

$ sudo apt remove brltty

• Restart the IDE and choose your board. The port menu should be available.
