Programming an FCB1010 with a Mac

Basic question: I have a Firewire 410 Audio Interface and I think there's issues with the Midi through when connecting the FCB1010 Uno and using the LG control software.

I am thinking the no communication thing is caused by either bad cables or the FireWire 410 audio interface. Being a complete newbie with Midi control, if I take the 410 out of the equation, would something like a MidiSport USB 1x1 be the proper cable to purchase to try and program through the mac?

I use a Midisport 2x2 with a Mac and the lg control with no problem.

I am foggy on connectivity. For programming you just go out of the FCB into the IN on the Midisport and Out of the mIdisport to the IN of the FCB?
