MICROBIT SU UBUNTU

 # Create rule

sudo cat << EOF >> /etc/udev/rules.d/50-microbit.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="0d28", MODE="0664", GROUP="plugdev"
EOF

# Add current user to plugdev group
sudo usermod -a -G plugdev $USER

# Reload udev rules
sudo udevadm control --reload-rules

Afterwards restart Chrome and reconnect your micro:bit.

sudo bash -c 'echo SUBSYSTEM==\"usb\", ATTR{idVendor}==\"0d28\", MODE=\"0664\", GROUP=\"plugdev\" > /etc/udev/rules.d/50-microbit.rules'
