====== Making custom udev entries ======


<code># udevadm info -a -p $(udevadm info -q path -n /dev/ttyUSB0)| grep ATTRS{serial}
    ATTRS{serial}=="A9KJB1T5"
#</code>

create a file in /etc/udev/rules.d/
<code udev 99-arduino.rules>SUBSYSTEMS=="usb", ATTRS{serial}=="A9KJB1T5" , KERNEL=="ttyUSB?", SYMLINK+="sump",  GROUP="dialout"
</code>

Then, reload the rules,
<code>~# udevadm control --reload-rules</code>
