Adem, scanModem only detects PCI devices and some USB devices: A candidate modem is not evident among the PCI devices: Attached USB devices are: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port However, You may try to see if your modem is detected and made available through usb_serial, please try $ sudo wvdialconf /etc/wvdial.conf and let it scan for a modem port hopefully it finds one like /dev/ttyUSB0 or similar that can access the modem. Please run above command and let us know if it detected the modem or not.
