Help with configuring

Help… I am a new user.
I have my software running “Cubase LE AI Elements 8” on my MacBook Pro, and I am trying to connect to my new Yamaha MG20XU mixer. I downloaded the latest driver from the website, and I ended up with a new icon on my launchpad …(is this normal?) I attached a pic of it.

Also, I cannot get the channels on my mixer to show up in the device menu? I assume I should see them when connected?? I attached a pic of that too.

Am I wrong??

OK…so it looks like it is connected OK.

The USB interface of that mixer only has 2 inputs and 2 outputs. It doesn’t have individual channel recording or playback.

That is a real disappointment …

The newbie got fed some bad info.

I might as well just use GarageBand!
