Ok, USB is not really an option at this point, must be an Amiga One deal leftover in the guide. USB, It's not recognized at this point. But hey, I wondered if drivers were being loaded for this stuff from the CD.
So you are safe with 'Amiga' option. And unchecking it seemed to work fine with my old Micronik adapter too, with PC keyboard.
More beer, onward...
