I upgraded the ubuntu on my laptop from 12.04 -> 12.10. In 12.04, I followed the installation procedure for linux. Whenever i connect the USB dongle, the application launches on detection and I can connect using the GUI window.

I upgraded to ubuntu 12.10, when I am connecting the dongle. The device is not detected.

After this i tried the usb\_modeswitch method, adding the rule in the /lib/udev/rules/40-usb\_modeswitch\*\* with the vendor and devid. I can see in the "dmesg" the modem detection as:

```
[ 2111.508851] usb 2-1.4: new high-speed USB device number 16 using ehci_hcd
[ 2111.609813] usb 2-1.4: GSM modem (1-port) converter now attached to ttyUSB0
[ 2111.610163] usb 2-1.4: GSM modem (1-port) converter now attached to ttyUSB1
[ 2111.610476] usb 2-1.4: GSM modem (1-port) converter now attached to ttyUSB2

```

I created a connection in the network\_configuration and re-connected the USB dongle, but still connection is not activating in the Network Manager.
