i just got a USB-modem Huawei E392. I am running Ubuntu 12.04. When i plug the usb modem into my laptop nothing happens. It is detected as GSM Modem/Networkcard, when i run the "lsusb" command in a terminal. It is shown in Network connections as HUAWEI-E5172-ACA4, under the wireless tab. But i'm not shure if it is my usb-modem.
