sudo cp 50-ioio.rules /etc/udev/rules.d
sudo /etc/init.d/udev restart
You should get back either IOIO0 or IOIO1. Note if this doesn’t work, you may also try:
Step 3. Install a Java Runtime Engine, OpenJDK 7 has been tested, most likely other will work but have not been tested. Note the PIXEL PC GUI app does require JRE 7 or higher.
sudo apt-get install openjdk-7-jre
java -Dioio.SerialPorts=IOIOX -jar app-name.jar where x is the port # from step 2
Ex. java -Dioio.SerialPorts=ttyACM0 -jar pixelc.jar --gif=your_animation.gif
