Mac and Yamaha 206CUSB missing ports

I’m in audio recording and just buy a Yamaha 206CUSB and Cubase AI5 came with it.
After I install everthing and run Cubase AI5 it says that the input Ports are missing: Steinberg CI2
I did find this devices in the Mac.
The even strange thing is that with another DAW I can record!
Thank you in advance for your help.

Follow the setup guide.

Make sure you have the proper ASIO driver selected in device setup.
