Hello, The same problem exists in Kubuntu 13.10 with Huawei E173 and Dell Latitude E6430. Only storage is active.
See the following scenario: 1) turn on the computer, log in 2) connect the USB modem Huawei E173 3) The modem is not detected (see the following commands): % lsusb|grep -i huawei Bus 001 Device 005: ID 12d1:1c0b Huawei Technologies Co., Ltd. E173s 3G broadband stick (modem off) % ls /dev/ttyUSB* no matches found: /dev/ttyUSB* To activate modem run: 4) remove the USB modem Huawei E173 5) Run the following command to load usbserial module (see correct vendor and product code): # modprobe -v usbserial vendor=0x12d1 product=0x1c08 6) You can also turn on usb_modeswitch logging: # diff /etc/usb_modeswitch.conf-ORG /etc/usb_modeswitch.conf 19c19 < EnableLogging=0 --- > EnableLogging=1 7) connect the USB modem Huawei E173 again 8) The modem is properly detected: # lsusb|grep Huawei Bus 001 Device 007: ID 12d1:1c08 Huawei Technologies Co., Ltd. # ls /dev/ttyUSB* /dev/ttyUSB0 /dev/ttyUSB1 # tail -n 20 /var/log/usb_modeswitch.log Mode switch succeeded. Bye. ok:12d1:1c08 -------------------------------- (end of usb_modeswitch output) Checking success of mode switch for max. 20 seconds ... Reading attributes ... USB dir exists: /sys/bus/usb/devices/1-1.2 Warning: USB attribute "serial" not readable. All attributes matched Mode switching was successful, found 12d1:1c08 (HUAWEI: HUAWEI Mobile) Now checking for bound driver ... driver has bound, device is known Checking for AVOID_RESET_QUIRK kernel attribute AVOID_RESET_QUIRK activated All done, exiting 9) Now you can correctly connect using e.g. wvdial via /dev/ttyUSB0. 10) However NetworkManager detects the wrong device /dev/ttyUSB1 # nmcli dev|grep ttyUSB ttyUSB1 gsm rozłączono and it is not possible to connect the internet using the graphical network manager in KDE (Kubuntu 13.10), but with wvdial and /dev/ttyUSB0 it works fine. Regards, Pawel. PS. Sometimes running the following command works fine, but not always (I don't know why). # usb_modeswitch --default-vendor 0x12d1 --default-product 1c0b --target-vendor 0x12d1 --target-product 0x1c08 However when it finally activates modem properly, the network manager finds the correct device /dev/ttyUSB0. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to modemmanager in Ubuntu. https://bugs.launchpad.net/bugs/1057186 Title: Modem Huawei E173 works in 12.04 but not in 12.10 Status in ModemManager (with NetworkManager support): Fix Committed Status in “modemmanager” package in Ubuntu: Confirmed Bug description: Modem Huawei E173 works in 12.04 but not work in 12.10.
