I just got a Plugable USB 3.0 7-port hub with dual charging ports and have connected it to my iMac Pro. I plugged in 6 MIDI controller devices. Four of them are working. But I have two Evolution U-Control UC-16 MIDI controllers that do not show up on my Mac. They do show up if I take the same cable out of the Plugable hub and plug it directly into the Mac. What’s the problem?
Also, I pressed ‘start’ on Plugdebug but it never wrote a file to my Desktop.
In Terminal, top shows that it is sleeping.
