Hello Aleksander, The Queltec UC20 modem is sitting on my development board PCIe bus. When I issue the command udevadm info /dev/ttymxc2 I am getting response:
root@linaro-alip:~# udevadm info /dev/ttymxc2 P: /devices/soc0/soc/2100000.aips-bus/21ec000.serial/tty/ttymxc2 N: ttymxc2 E: DEVNAME=/dev/ttymxc2 E: DEVPATH=/devices/soc0/soc/2100000.aips-bus/21ec000.serial/tty/ttymxc2 E: ID_MM_CANDIDATE=1 E: MAJOR=207 E: MINOR=18 E: SUBSYSTEM=tty E: TAGS=:systemd: E: USEC_INITIALIZED=8343793 root@linaro-alip:~# Also the command mmcli -L reports: No modems were found. Do I need to create udev rule for this device? How the udev rule should look like for this device? Also after connecting to modem through Kermit I can issue AT command and see the mobile networks.

What is the device hooked up to on the machine itself? ModemManager does not usually auto-probe various platform drivers, because it cannot know that a modem is connected as these are not USB/PCI/etc and either do not provide device identifiers, or the device is a generic serial adapter which doesn't necessarily indicate a modem either (eg, it could have a UPS attached or something). So generally for these devices, if you have one you know what you are doing, and you can add a whitelist entry for it quite easily with udev rules. But let's confirm the details first.
