Nomad and usb faders on Mac

Hello

I'm looking for a way to use an USB MIDI interface on my nomad.

With Cobalt Nomad PC, I can use a nanokontrol2 Korg. that does not work with Cobalt Nomad Mac.

Is there a way to connect this USB device which send midi information only by usb ? on PC ? on MAC ?

thanks for your help

this device doesn't have physical MIDI port, and doesn't have a config to send OSC.
