The print is ok.  It's called like this:

   328          /* Check if user has supplied the dongle id or not */
   329          if (!dongle_id)
   330                  dongle_id = via_ircc_read_dongle_id(self->io.fir_base);
   331          self->io.dongle_id = dongle_id;

If you don't use a module id then it acts like an IBM dongle by default.
