Minor Versionm

by Frank Rupert Catapang


This article explains how to enable USB/Serial Port Permissions on Linux OS. Please note: you will only need to do this if you’re trying to update P/P+ firmware and experience errors.

    • Note: Linux distributions other than Ubuntu may run into issues with the following instructions: 

    • Install the following package by entering: sudo apt-get install libgconf-2-4

    • Add yourself to the "dialout" group: sudo usermod -a -G dialout $USER

    • Create a rule file to automatically enable permissions when Palette is connected: sudo nano /etc/udev/rules.d/50-local.rules

    • Paste this line in the file you just created: ACTION=="add", ATTRS{idProduct}=="0042", ATTRS{idVendor}=="2341", DRIVERS=="usb", RUN+="chmod a+rw /dev/ttyACM0"

    • Press Control-O and then Control-X to save the file and exit.

    • Note: you may need to log out and log back in (or reboot your computer) for the changes to take effect.
