New Digi not detected (following)

I cannot reply to the previous topic I created. Basically the digi does not work (see http://www.hifiberry.com/forums/topic/new-digi-not-detected/#post-10480).

As suggested I tried to remove any blacklist entry from modprobe.d, but there is nothing related to the digi (i.e.: blacklist i2c-bcm2708) in any file.
