FS#2641 - Device file for USB does not appear /dev/ttyUSB*

With new version 19.7.0rc I could not make my USB cellular (3g) modem dongle to work due to it simply no any serial device like /dev/ttyUSB* file appear with insertion.
In kernel log it appears report about new device insertion and nothing happenings after.
I made several attempts, with ‘modeswitch’ or without and several other ‘mods’ the result is the same no any /dev/ttyUSB*
With other version it was not such problem it appeared exactly three /dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 es well as on my Ubuntu 19.04 And Ubuntu 16.04 Ubuntu 18.04

Both router and dongle are USB-2
Actually router is Asus RT-N16
and modem dongle is Alcatel One Touch X090S

P.S. I need this one to be solved to report other bugs. :)

It's already 19.07.0-rc2, same problem remains.
I just "forgot", that it is good idea to add a log

Just ones again it's a log after removing and insertion of a usb cellular modem dongle withsame namings of 'kmods' installed as I used with 18.06. (I need 19.07 because of 'tor' 4.*.)
