Aribaaaa!
I went for a NEW and BRAND clean Ubuntu 12.04.3 install since my tests so far has been experimental to learn about Ubuntu, XBMC and other media/PVR-related stuff under Linux.
And you know what..... UFO! Your driver works now and loads properly!!
dmesg | grep -i ddb shows now the following:
[ 2.555903] ngene-octopus-test: 406ffecccbec6e22da954a07b7398292330bc767 ddbridge: Add ID of Digital Devices Octopus V3.
