Minifuse 4 Inputs 3 and 4 not shown in Logic 9

[Tm57]

Hello,
I installed the Minifues 4 on an Imac of a friend. In Logic 9 I see only Input 1 and 2 but not the rear Inputs 3 and 4- I'm usualy not a Logic user and I don't know if it's a Logic or a Minifuse issue. Thanks for your advice
best regards Thomas

Have you tried to configure the Audio Midi app that comes with MacOS?  Sometimes the extra I/O can be propagated there.
