Unable to install Conexant USB modem type 0572:1340 in Ubuntu 18.04

I am new to Linux. I 've tried to install drivers for my Conexant FU07 USB modem but neither the Linuxant drivers nor the installer CD ones (dgcmodem_1.13_i386.deb) get properly installed.

The scanModem tool did not find much about the modem.

The lsusb output is:

Bus 002 Device 004: ID 0572:1340 Conexant Systems (Rockwell), Inc. 

The dpkg --list | grep --ignore-case dgc output is:

ii dgcmodem:i386 1.13 i386 Conexant DGC USB modem driver

And relevant part of the dmesg output is:

[19432.393516] usb 2-1.3: new full-speed USB device number 4 using ehci-pci
[19432.522961] usb 2-1.3: New USB device found, idVendor=0572, idProduct=1340
[19432.522968] usb 2-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[19432.522972] usb 2-1.3: Product: USB Modem

[19432.544244] cdc_acm 2-1.3:1.0: ttyACM0: USB ACM device

How should I proceed?

Your modem is now installed correctly as per:

dpkg --list | grep --ignore-case dgc output:

ii dgcmodem:i386 1.13 i386 Conexant DGC USB modem driver

And relevant part of the dmesg output:

[19432.544244] cdc_acm 2-1.3:1.0: ttyACM0: USB ACM device
