If you are reading these lines, you are certainly desperate because you are unable to make your computer communicate with your last internet purchase : a compatible (x)uino board from China. The (x)uino boards have, for the most, two distinct groups of circuits : the microcontroller and the USB / Serial adapter. It's is on theeses we are pesting in these lines. There are several circuit families and, the Arduino distribution (Arduino IDE) does not offer all the drivers of these exotic circuits. You will find below the drivers of different families of communication circuits.
