Question: I recently switched from Win 7 to Ubuntu 12.04...Best day of my life :)

I have a question relating to my Vodafone K3772-Z USB modem. When I plug it in, the lights start flashing on the device, meaning that it is functional. In the network menu I get a "Wired network Vodafone K3772-Z disconnected". I have set up the a connection by using Edit connections -> mobile broadband -> Add, but in the add window the "Create a connection for this mobile device" is blanked out and says "Any Device".

Does anyone perhaps have an idea of what I could do to get it working?

Answer: 
TO detail the above for vodafone data card K3372, Create a file name by using terminal (or CRTL+ALT+T) and type `sudo gedit /etc/usb_modeswitch.d/12d1:1526` now add the following code:

```
TargetVendor= 0x12d1
TargetProduct= 0x14bc
MessageContent="55534243123456780002000080000a11062000000000000100000000000000"

```

and save the file.

Now in the terminal type the following: 

```
sudo gedit /lib/udev/rules.d/40-usb_modeswitch.rules

```

Copy the line that contains "12d1" and "1520" (or any other line), paste/insert it somewhere else and change the second value from "1520" to "1526".
You can use [SAKIS3G](http://www.sakis3g.org/) to form a connection without unlocking it. I never unlocked the device and it worked fine. 
NOTE: I could also use another network's sim on a network locked device using SAKIS3G.
