I cannot get input or output with Logic using Presonus Studio 68c. The 68c is selected as the audio device in Logic. Mic input levels show up on the 68c and can be heard coming from the studio monitors connected to the 68c, but the audio does not show up in Logic. No playback can be heard from Logic either. I have checked the I/O settings in Logic and in Universal Control. My computer is iMac 2014 with Mojave.
