ttyACM0 is missing [closed]

Question

I've been searching for a solution, but couldn't find it here or wherever. I don't know if it's exactly programming, as is about arduino, but here it goes. I have a FREEDUINO UNO board (pretty similar to ARDUINO UNO, but from bq), which perfectly worked on Arduino 1.6.5 two days ago, BUT today it doesn'. Apparently, the port is missing, the port itself was ttyACM0, in /dev/. In fact I have no option of choosing a port available. I'm using Ubuntu 14.04.

I already tried:

• all searching methods in /dev/ of ttyACM0 and ttyUSB0 in the terminal, it's not there.
• group
• dialout (and permisses and all about this option, is done)
• lsusb
• reboot
• start from root
• unplug and plug, and plugging in different ports

I would appreciate every solution which doesn't implies "unistall and install the Arduino" "have another version" or even "another ubuntu", cause it worked fine, and it can verify code and all of that. Also my board blinks when connected so is not dead. I hardly think 16u2 is dead.

Help please, and thank you!

Answer 1

I solved this problem using Data & Power USB Cable

Port ttyACM0 not appear if you only use Power USB Cable

Answer 2

This took me hours to figure out but my power/data cable was not pushed all the way in. Even though light was on. Making sure it is inserted properly. Fixed everything.
