Installing Digicom DigiTune S USB key

[SteMMo]

Hi all,
i'm trying to install Digicom DigiTune S USB key.

Linux ghilba 2.6.32-26-generic #48-Ubuntu SMP Wed Nov 24 09:00:03 UTC 2010 i686 GNU/Linux

Inserting the key i see:
[ 3233.008095] usb 1-4: new high speed USB device using ehci_hcd and address 4
[ 3233.145186] usb 1-4: configuration #1 chosen from 1 choice


stefano@ghilba:~$ lsusb

I typed:
sudo modprobe dvb-usb
sudo modprobe dvb-usb-vp7045


stefano@ghilba:~$ lsmod | grep dvb
dvb_usb_vp7045 7403 0
dvb_usb 14457 1 dvb_usb_vp7045
dvb_core 86206 1 dvb_usb

I have no devices under /dev/dvb or similar ....
I installed kaffeine but it doesn't see any source

Any idea ?
