How to link node name with a custom name

1. run next cmd to see the port device

   $ udevadm info -a -n /dev/ttyUSB0  $(udevadm info -q path -n /dev/ttyUSB0)
   

2. Then open (or create) a file in /etc/udev/rules.d/ (named, for example, serial-symlinks.rules), and put the udev rule there.

   $ sudo subl /etc/udev/rules.d/serial-symlinks.rules
   

3. …you can write this rule:

   ACTION==”add”, ATTRS{idVendor}==”0403”, ATTRS{idProduct}==”6001”, SYMLINK+=”tty-xxx” //some attrs to lock specific USB device

then your ttyUSB0 can using the new name “tty-xxx”

1. and restart udev using

   $ sudo service udev restart

$ udevadm info -a -n /dev/ttyUSB0
$ sudo subl /etc/udev/rules.d/serial-symlinks.rules

modify the file

$ sudo service udev restart

using following cmd check it

$ ls /dev/tty*
