Serial ports greyed out on Linux

Development Tools IDE 1.x
1

Hi,

I am working with an arduino for my first time. I am using the DUE on Linux Ubuntu 16.04. Tools > Port > Serial ports is greyed out. I understand this is an issue that has come up for others before, however I am not able to use their suggestions to solve my issue. I have given myself permission to the ports and added my user to the dialout group.

The arduino-1.6.11 folder in currently in my /home/ directory and I am not in root mode. Any suggestions would be very appreciated since this keeps me from using the serial monitor!

Same here on Archlinux OS and Arduino UNO.
I checked that a new device appearing in /dev, but is not a ttyACM0. Even symlinking it, the result is not working.
I've create a udev rule in /etc/udev/rules.d/97-Arduino.rules

SUBSYSTEMS=="usb", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="0043", GROUP="users", MODE="0666", SYMLINK+="ArduiUno"

And the symlink is appearing.

$ ls -l /dev/ArduiUno
lrwxrwxrwx 1 root root 15 26 ago 16.22 /dev/ArduiUno -> bus/usb/003/015

The weird is that was before working as per /dev/ttyACM0 even the created link. Today I was trying to make some sound off the pin 13 and after connecting a loudspeaker with 560 Ohm in series, the data LED remain orange, not blinking as before.
Even pressing reset several times and restarting the Arduino UNO, nothing changed.

Solved !!
My bad, I got an update and I didn't restart the machine. So the kernel was unrelated with the modules.
After restarted everything gone back to normal :wink:

I am on Linux Mint 18 and Arduino ide 1.6.5 and I would have to go to:

Tools/Boards/ Boards Manager/

Then install the SAM boards by clicking on the more info
selecting Install.

You can check your 2 usb serial ports from the DUE this way.

Plug in each DUE USB serial Ports and do :
lsusb
then do:
dmesg
And then:
tail /var/log/syslog

You should see something like this. I am using an Uno.
~ $ lsusb

I've checked these things and it's working now.
But for some reason the kernel try to switch from ttyACM0 and ttyACM1. It's obnoxious to go to the menus and select the new port.
Probably this fact is due by unplugging the cable while the Serial monitor still holding the previous driver. So when I plug the cable back kernel will assign a new port name.

My rule is working correctly, but I can't find any configuration to tell the IDE to use it.

Arduino 8266ESP for Mint18

Before you do anything, check the usb cable. Sometime they do not support all
contacts, that was the error in my case.
prereqquisites: Arduino IDE
Check boardinformation

End IDE before flashing!

Terminal:

ls -la /dev/ttyUSB*

Hi, because I have not found a solution for my problem and want to help others, if they are in the same situation. Ok it is 2 years ago, but is this a problem??

Thanks for your hint.
