Pierrelux, please read this topic published by water01.
It may well be the explanation of what happened to you.
Advice for all: If you are not sure that your Arduinos have a non counterfeit FTDI chip, don't actualize the FTDI drivers. If you do it, and your Arduino have a counterfeit FTDI chip, the new drivers will make your Arduino unusable. It is not bricked, but the new drivers will change the PID to 0, so the device does not work. Can be possible revert the PID back to it's original value, but this is out of this article, and for now I also don't know how to do it.
