How to 'talk' to USB modem in Ubuntu 12.04 after being found with lsusb?
 
I have a USB modem that is identified in Linux (Ubuntu 12.04) with lsusb as

Bus 001 Device 003: ID 0572:1329 Conexant Systems (Rockwell), Inc.

My question: How to talk to that device (e.g. with microcom etc?)? What dev device should I use? There is no /dev/ttyUSBXXX available and just one /dev/ttyACM0. Is it the ACM0? How to know?

You may want to take a look at USB_ModeSwitch (http://www.draisberghof.de/usb_modeswitch/). It may already be installed on your system. If I remember correctly, Conexant modems need to be switched-out and that's what USB_ModeSwitch does.

Also, you may need drivers for it; refer to http://www.linuxant.com/drivers/dgc/index.php for information.

Hope this helps some.

On the site tronayne mentioned there's this page:
http://www.linuxant.com/drivers/dgc/install.php

It gives steps,... step-by-step, for setting up the Conexant modems...

I have a usb modem and the correct driver for it is /dev/ttyACM0. Select it as your modem and if it isn't the correct driver you will get modem errors, when dialing out. Here is a link to how to dial out.
