</span>Depending on the brand it will either be /dev/ttyUSB0 or /dev/ttyACM0<br>
look at the end of the 'dmesg' command to see what device it was<br>
assigned when it was plugged in (replug if necessary).<br>
<br>
you will also need permission on the device, i dont know about that<br>
ubuntu specifically but if you do an 'ls -l' on the device file you will<br>
usually find its in group 'dialout' or 'uucp'<br>
<br>
which ever it is, add your username to that group in /etc/group<br>
when you login again yu should now have write permission to those files.<br>
<br>
check to see if ModemManager is running, if it is ypu need to kill it,<br>
and disable/uninstall it somehow, it is a bit dumb and assumes that all<br>
serial ports have modems on the end of them, grabs the serial port and<br>
shoves AT commands down it, so kill it off.<br>
<br>
with all those fixed you should have more luck<br>
you can also use the 'serial monitor' feature inside the arduino editor,<br>
it doesnt have to be an arduino connected, its just a serial terminal<br>
program.<br>
