Works well straight out of the box but requires the use of sudo. Thankfully this is easy to fix as root (usesudo -i) execute the following:

echo "SUBSYSTEM==\"usb\", ATTRS{idVendor}==\"1781\", ATTRS{idProduct}==\"0c9f\", GROUP=\"adm\", MODE=\"0664\"" >> /etc/udev/rules.d/72-embedded-dev.rules
service udev restart

This gives all users read access and users in the adm (eg anybody who can use sudo) r/w access. If you don’t care about using a group just set the mode to 0666 to give all users r/w access.
