Serial port menu all grey (and empty)

Hello everyone!

(English is not my native language, so don't hesitate to ask me to reformulate my sentences :stuck_out_tongue: )

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 ?
at processing.app.Serial.(Serial.java:191)
at processing.app.Serial.(Serial.java:77)

at processing.app.Editor$DefaultExportHandler.run(Editor.java:2346)
at java.lang.Thread.run(Thread.java:701)"

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...

Any ideas?

Thank you for your help! :slight_smile:

Have you loaded USB drivers?

The USB to Serial chip has been damaged or needs to be reprogrammed.

If an official Arduino with a ATmega8u2 or ATmega16u2, then try these directions:

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).

If so, how does it works on my other PC?
I have a Funduino Uno (https://www.foxytronics.com/products/265-funduino-uno-r3), it can maybe help?

I missed that point.

Maybe the data lines of the USB have been damaged. Does it work on other ports of the broken computer?

Both the USB ports and the eSATA ports doesn't work.

(I didn't know if the eSATA is supposed to work with the Arduino, but I tried anyway :slight_smile: )

Maybe the problem is the computer.

How can I be sure of that, and identify the problem's origin?

Right click on "Computer", click on "Manage", check "Device Manager" to see what ports are working.
