How can I connect my Operator device on Linux under a non-root user?

The Operator devices are USB CDC ACM devices, so in order to properly access them you should have read/write access to the serial device on your Linux computer.

 

For Debian/Ubuntu users:

sudo usermod -a -G dialout $USER
sudo usermod -a -G plugdev $USER

Then logout of your user and log back in. Now you should have access to the USB device as a non-root user. This command adds your user to the dialout group and to the plugdev group.

The dialout group is needed for ACM devices and the plugdev is to mount (only with the options nodev and nosuid, for security reasons) and umount removable devices through pmount.

 

In addition to this, create a file in /etc/udev/rules.d/99-epilogue.rules with the following contents (thanks to Tim Boalch and Horia for submitting this):

# GB Operator
SUBSYSTEM=="usb", ATTR{idVendor}=="1d50", ATTR{idProduct}=="6018", MODE="0666", GROUP="plugdev"

# Epilogue DFU
SUBSYSTEM=="usb", ATTR{idVendor}=="1209", ATTR{idProduct}=="db42", MODE="0666", GROUP="plugdev"

 

For Arch/Manjaro users

Thanks to u/CrayolaFanfic from Reddit for submitting these!

sudo pacman -S glibc
sudo pacman -S qt5-base (might not be necessary)
sudo usermod -a -G uucp $USER

Then restart your computer.

 

For Steam Deck/SteamOS users

Thanks to u/phncx from our subreddit for submitting this!

sudo usermod -a -G uucp deck
sudo reboot

"sudo reboot" will restart your Steam Deck.

 

Note:

We do not recommend running the application using superuser privileges as we use pulseaudio to output audio. If you run the application using `sudo` the Playback app might not be able to connect to the pulseaudio daemon properly and you might not have audio while playing. Also, we do not recommend running it as root user. Instructions above are for non-root users. Thank you!
