Arduino recognized as ttyACMx in Raspberry Pi

Arduino devices (after UNO) connected to Raspberry Pi, or most Linux,  via USB, will be recognized as ttyACMx. It can be ttyACM0, ttyACM1, ttyACM2...etc.

To check the assigned number (ttyACMx) in Raspberry Pi, or Linux, enter the command after Arduino inserted.
$ dmesg|tail
Arduino Due recognized as ttyACM0 in the example

It can be noticed that ttyACM0 is added under /dev folder.
$ ls /dev/tty*

And more entries added in usb list.
$ lsusb
