Yes, but still have no idea how I can recognize the ports to which a
device is connected. The records of the both differ only here:

Bus 004 Device 002:
Bus 005 Device 006:

How do You convert the addresses into physical ports - if I have
understood You correctly?

In "lsusb -v -s 004:002" there should be an iSerial field. Maybe
that has a non-zero value in it?

The -t option shows usb topology:

I do have the field, - for both devices it is the same.

That's true, but it helps me a little, as the devices have the same IDs
only diver bus/dev topology differs. I can see the ports the devs the
modems are connected to, but can not discern between the modems and
the OS devices as it is defined at the reboot time (i.e. /dev/ttyUSB*).
