I'm trying to configure 3G USB modem in my CentOS 5.7 instance that I have installed on VirtualBox (Win7 x64 is my main system).

First of all I'd like to configure a dialer in /etc/wvdial.conf

[Dialer aero2]
Modem = /dev/ttyUSB0
Phone = *99#
Username =;
Password =;
Init1 = AT+CGDCONT=1,"IP","darmowy","",0,0
Auto DNS = on

The thing is that I can't figure out what's the equivalent of ttyUSB0 under VirtualBox hosted linux. I don't have anything like /dev/ttyUSB0 but the modem itself is being detected (as I can view contents of the dongle, etc).

Any clues?

This question came from our site for system and network administrators.

Check output of dmesg to see what devices are created. Probably you will have to use usb_modeswitch program ( to enable modem functionality on device.
