Hi,
I am a technical instructor and I've been delivering training sessions in several locations all over the world. Some of them had Promethean boards but I was unable to use them as you did not release the working drivers for Ubuntu 14.04. It is one of the most popular Linux distro and also a LTS so I think it is understandable to add its support. Please fix it ASAP as it will make my (and also others) work much easier.
Consider the fact that more and more IT specialists are moving towards Linux.
