The following code will initialize a USB-arduino connection . Please note that
in order to make this initialization function work, it is necessary to
set the permission for the ttyUSB device to 0666. You can do this by
adding a rule to /etc/udev/rules.d
As root (using sudo or su), copy the following text into a new file in
/etc/udev/rules.d/94-ttyUSB-rules
KERNEL=="ttyUSB[0-9]",MODE="0666"
You only have to do this once.
