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: 
This worked for me.

This is for new vodafone data card, model K3772. I had the problem of getting detected, Follow these steps, it really worked for me (not tested with model no:k3772-Z as my model is K3772):

Create a file named 12d1:1526 in the folder `/etc/usb_modeswitch.d`.

Edit it and fill it with this text:

Code: 

```
TargetVendor=  0x12d1  
TargetProduct= 0x14bc

MessageContent="55534243123456780002000080000a11062000000000000100000000000000"

```

Now edit `/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.

That's it.
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.
