37.13 PyBoard via Serial User Access
See https://github.com/micropython/micropython/wiki/Board-STM32F407-Discovery#programming-from-linux-via-dfu to set up udev rules that will change the serial device’s permission to allow all users access once the device is plugged in.
Essentially,
to add the contents:

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", MODE:="0666"and restart udev:
and the next time the device is plugged in:
