How switch UR28M to CC mode on firmware 2.0?

I’ve just upgraded to firmware 2.0. And everything works well.
But how I can switch UR28M to CC mode?
It doesn’t recognized by Cubasis on iPad (3rd gen), when connected through cck.

For the lazy ones
Hold down C (output) and turn on the device.
The input and output level Meters will flash.
To turn off CC mode for iPad do the same again.
