ATC arduino Linuxcnc 2.8

Hi.
I'm trying to build an atc for my mill.
I found this GitHub - mardini1974/ATCduino: Automatic tool changer for Linuxcnc with Arduino UNO
but it has only 8 stations.I will expand later to 20 stations if it works.
I install the atc on linuxcnc 2.8 on debian wheezy and i get only this:
Found ATC (Auto tool changer) and connecting on port
/tty/USB0.................................................................................................
...................................................................................................................................
.................................................................................................................................

and i waited 15 min and it goes forever.
I think it is missing something.
I did the instalation from the instructions on the github.
Anyone has any idea?

What does
$ dmesg |grep -i "usb"
from the command line say?
Also:
$ lsusb
?

cnc@cnc:~/linuxcnc/configs/frezz$ dmesg |grep -i "usb"

i used the arduino serial terminal and it comunicate just fine.
The arduino is closed when i startup the linuxcnc.
Maybe something with the Python serial plugin?

Possibly, but I'm Python ignorant, sorry, good luck.

Ok.thanks for the replay.
