Hello, I have 2 arduinos, an original arduino and a generic. original for the use of the projects, plus the complex and the arduous generic use of the simplest projects, but Im programing in operating system ubuntu LINUX. Have the driver Search on Google and say that I should not have a problem, but still, and only the links to download the driver are shown but no instructions on how to install it and I would like to know if you can help me with my problem.
