When I connect my phone Xperia Tipo to my Ubuntu 12.04, the USB icon does not appear in a launcher.

lsusb gives me following results:

I installed Wammu and it does not see phone either:

Wammu is now searching for phone:
All finished, found 0 phones
No phone has been found!

On the phone I have debbugging turned on and it sees Ubuntu.

Can I ask for instruction step by step? I am a begginer on Ubuntu.
