====== UDEV RULES ======

===== RULE FILE FOR USB TO SERIAL =====
<code bash>
$sudo touch /etc/udev/rules.d/99-usb-serial.rules
# 99-usb-serial.rules content :
SUBSYSTEM==TTY, ATTRS{idVendor}=="xxxx", ATTRS{idProduct}=="yyyy", ATTRS{serial}=="ssss"
SYMLINK+="TheNameIwant",MODE="0777"
</code>
<code bash>
$sudo udev restart
</code>

Will create ''/dev/TheNameIwant'' when pluging in the usb-to-serial adaptor.

===== SUB-TO-SERIAL RIGHT ISSUES =====
<code bash>
# add "userName" to the "dialout" group
$sudo adduser userName dialout
# or
$sudo usermod -a -G dialout $USER
</code>
