I have an arduino uno since april and it worked fine until a few days ago. Now I have troubles to upload my sketches. The IDE says that the serial port is not found, suggest to select the right one in "tools" > "serial port" and adds this:
"processing.app.SerialNotFoundException: Port série « /dev/ttyACM0 » non trouvé. L'avez-vous bien sélectionné dans le menu Outils > Port série ?

In tools, the serial port menu is grey, I can't click on it.
The "fun" part is that the problem occurs on all my OS (Win7, two linux and one live linux) on my laptop, but the transfer works fine with my other PC on Win7...
Yes, I tried the steps from the troubleshooting guide, both for Linux or Windows. it happened more or less when I did an update on my main distribution (Linux Parsix, based on Debian), but I still can't figure out why it can change anything in Windows or the other Linux (even on Live USB).
