I have two EC25-EUX modules and they're connected to a 4-way USB hub and the hub is connected to a NanoPi with Ubuntu server 20.04. By entering
ls /dev/
command 8 ttyUSB ports are shown(from 0 to 7) and with
udevadm info --name=/dev/ttyUSBx
command the list of ports attributes are shown and attributes are same for all the ports. Also I have a rule file which maps one EC25 ttyUSB ports to Ubuntu command and diag ports by using ttyUSB attributes. I`m searching for a way or an specific attribute which i can distinguish ttyUSb ports of each EC25 modules.
