[chirp_users] Permissions for serial device under Linux
I am running Ubuntu 16.04 under crouton on an Asus Flip C302 Chromebook. For the most part this setup works great on most everything except access to the tty device. I have added myself to the dialout group, but I still need to manually do a chmod on /dev/ttyUSB0 in order to avoid the permissions error. It is not a big problem to do this, but I thought that if I were in the dialout group, that would allow me to use the serial port without the chmod. Can anybody tell me what might be going on?

Hello Pat,
Please send the results as your user account of these commands in Terminal before doing any chmod:
groups
ls -l /dev/ttyUSB0
Then do your chmod command - send the command as well, and send the results of ls -l /dev/ttyUSB0 again.
See if we can figure out what is going on. Thank you,

I found that I needed to be in the 'serial' group rather than 'dialout'.

Hello Nigel,
Different Linux distributions put tty connections in different groups.
ls -l /dev/ttyUSB0
Will always tell you which group owns the device.
Just add your user that that group and it will work.

I don't know what crouton is, but I don't have to chmod with Ubuntu Mate any versions. I mostly use 16.04.

It is a set of scripts that allows you to chroot Linux on Chrome OS.
