sudo aptitude install gnome-ppp

Now fire-up gnome-ppp (It's on the Internet SubMenu), connect your MD300 to your computer, wait a few second to let your Ubuntu identify the new device (nothing will show up, but you can see the messages with dmesg command at the terminal). Now click Setup button and then Detect Button, close the Setup Dialog and Click Connect.
