I would try the following: 1. Plug in the device 2. Check 'dmesg | tail', it should have usb-storage related entry. 3. Load the usbserial module using the command in the previous mail. 4. Check 'dmesg | tail', it should have usbserial related entry. 5. Run 'sudo wvdialconf' and see whether it detects a proper modem.
