I installed Kannel in a server, and I want to use a GSM 3G USB modem to send/receive SMS messages, as described in section SMS Centers > GSM Modem of the Kannel User Guide.
I have already installed, configured and tested Kannel on my notebook successfully.
When I plug the modem into my notebook, a device named
appears. It acts as a serial port to send commands to the modem.
I have to put this device in the Kannel configuration file.
After some testing, I decided to install Kannel in the production server. The server runs Linux-VServer, and my task is to install Kannel on the host and PlaySMS in one of the guests, which runs Apache.
The problem is that I can't find any device analogous to the
ttyUSB0 that is created in my machine (and AFAIK, in all normal Linux boxes).
Here are some diagnostic commands. The modems used are not the same model, but I have already tested Sierra 308 on my notebook and it works, too.

The only previous question with a similar problem that I found here was How do I access a USB serial port without an entry in /dev?.
In his case,
dmesg said that
ttyUSB0 was created, which does not occur in my case.
Anyway, I have tried the solution posted there, using
mknod to create devices manually:
for i in 0 1 2 3 4 5 6 7 8 9; do sudo mknod /dev/ttyUSB$i c 188 $i done
I created all these devices because
lsusb says that the device is plugged in
Bus 008 Device 002.
It did not work. I tested it with
picocom, and this it says (to all these devices, not only
$ picocom - FATAL: cannot open /dev/ttyUSB0: No such device or address
While in my notebook,
picocom works fine:
$ picocom -b 9600 /dev/ttyUSB0 Terminal ready AT # my input OK
