How to grant full access to some user devices

• Create the file /etc/udev/rules.d/99-<my_device>.rules

# Device Brand/Model and any important info
 SUBSYSTEM=="usb", ATTRS{idVendor}=="1A2B", ATTRS{idProduct}=="3C4D", MODE="0664", GROUP="<distro_group>"

• Ensure the distro_group is set accordingly to the distro

• Fedora: plugdev group
• Debian: dialout group

• Reload udev

# udevadm control --reload-rules
