I am working on El Capitan and have never had issues. All of a sudden, my fader doesn't work right. I can record one pass of automation with the fader on a track, but once that's done, it won't move with the track or record any new automation. I tried to update firmware, but got what seems to be a very common error. I am plugging a Sabrant USB 2.0 hub into my Mac's 3.0 slot and the Faderport is connected there. I am running Universal Control 2.8 but also twied 2.9, 2.7 and many others. No fix. I can use all of the other controls just fine and R W T all change the automation parameter on the track in PT but the light doesn't come up. Running PT 12.
