Problems Connecting to serial Port :/dev/ACM0

edit

I've been stuck on this for a while my problem is I cant access GPS data for a ublox node. I am connecting to a Raspberry pi 3 that is running a RPI 2 Snappy Image. I am connecting to the PI through a SSH on a ubuntu 14.04 laptop.

I am running the following command and getting this error: (updated output with correct port spelling)

    ubuntu@ubuntu:~$ roslaunch ublox_gps ublox_device.launch 
... logging to /home/ubuntu/.ros/log/cefae814-d237-11e7-8ade-b827ebffc577/roslaunch-ubuntu-1799.log

I checked that the port was correct by using

cat /dev/ttyACM0

it outputted my GPS Data that I was looking for, I assumed that I was permission were off so I did the command

groups

this is the output

ubuntu adm dialout cdrom floppy sudo audio dip video plugdev netdev lxd

it says I'm in the dialout group, so i assumed my permissions were fine. when I do

ls -la /dev/ttyACM0
crw-rw-rw- 1 root dialout 166, 0 Feb 11  2016 /dev/ttyACM0

So there is a problem with my # after dialout its should be 666 right? I tried using

sudo chmod 666 /dev/ttyAMC0

No change to the permissions.

Does anyone know how to change the dialout 166 problem? thanks - or any other solutions that would allow me to open the port or read the GPS Data.
