How to configure HUAWEI E173 USB modem in Armbian (Ubuntu) to work via gammu (get ttyUSB*)?

Question

Huawei

I'm trying to connect and configure the HUAWEI E173 modem. It seems to have tried everything I found on the forums ... the problem is that it is displayed as 3 usb-storage in modem mode. I permanently switched AT to modem mode with the at ^ u2diag = 0 command from another machine.
dmesg

On the forums, I spied the logs of other people as it should be:

Answer 1

modprobe usbserial vendor=0x12d1 product=0x1001gives an error FATAL: Module usbserial not found
usbserial - a kernel module and it is missing in my Armbian assembly, but as I understand it, it is the key to connecting the modem, since communication with the modem goes through serial. I dug out some article in which there is a similar situation and there, to solve the problem, they rebuilt the kernel by adding this module, but for me it is still some kind of magic that takes time to study. On the manufacturer's website I found a new assembly of Armbian with the Kernel 4.19 kernel and it seems like with all the modules ... I haven't checked it yet, but I think the problem will be solved after the update.
