"""
Assuming to use Linux (Debian, Ubuntu, Raspbian, ...), it may happen that more RS485/USB adapters are connected to the same computer, 
but it's important to identify the serial port in a persisten way to avoid troubles: if they have the same vendor id, product id and serial number, 
you have to follow the step-by-step procedure: assuming that ttyUSB0 is used as dombus #1, and ttyUSB1 as dombus #2

    find the devpath for the bus #1, corresponding with ttyUSB0 in this example, running the command 
      udevadm info -a /dev/ttyUSB0|egrep 'ATTRS.(idVendor|idProduct|devpath)'|head -n3

    Assuming that result is

     ATTRS{devpath}=="1.5"
     ATTRS{idProduct}=="7523"
     ATTRS{idVendor}=="1a86"

    create/edit the file /etc/udev/rules.d/99-serial-ports.rules adding the line

    SUBSYSTEM=="tty", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", ATTRS{devpath}=="1.5", SYMLINK+="ttyUSBdombus1"

    to set that the USB/RS485 adapter plugged to the USB port 1.5 should be named /dev/ttyUSBdombus1
    Repeat the steps above for the next RS485/USB serial adapters, to set the device to ttyUSBdombus2, ....

    Run the command    systemctl restart udev   to load the new configuration, then unplug and plug again the RS485/USB adapters
