Cross 3.2 - problem with KORG ZERO 4 MIXER

Hello.
I have a strange problem: Cross 3.2 works perfectly with my KORG ZERO 4 mixer (built in FW soundcard) using my old WHITE MACBOOK (late 2007, Mountain Lion Osx)... but, using my new MACBOOK PRO (Osx Mavericks) Cross can not see all mixer inputs but only 1 and 2 (rather than 8 totals); all ok with all 8 outputs, instead. Why? Does someone has the same problem?
Thank you for your help.
