Following a firmware update on my Electra One MkII, the Electra desktop editor could no longer detect the controller when connected through my iConnectivity mioXL.
The controller worked when connected directly to my Mac, and the mioXL MIDI routing appeared correct in both directions.
Investigating Auracle X’s USB Host Reservation settings revealed that the original Electra reservation was still associated with:
electra.one Electra Controller EO-123456 (Port 1)
However, the updated controller was now detected as:
electra.one Electra Controller EO2-420d8183
The mioXL had consequently assigned it to an unreserved USB Host slot (HST 6), leaving the original Electra One slot disconnected. All my existing MIDI routes still referenced the original slot.
Hopefully this helps anyone experiencing similar connectivity problems after upgrading.
