Having the same issue here:
- FadePort Classic
- macOS 10.13.6
- Mid 2012 MBP w/ (2) native USB2.0 ports
I've tried multiple ports (both directly on the laptop and via a hub), and multiple cables. Still No luck.
Come on Presonus. A year and a half on from the initial post and loads of other people saying they're experiencing the same thing, and still no solution?
