MIDI Controller causes FL24 to hang on launch

[Yearofthegoat]

FL hangs on launch, unless I plug in my fader controller AFTER FL is up and running.

The device is (I guess) class compliant, as it needs no driver other than a generic MS one. It's a single fader, with a knob and a button. It's an Arduino in a box, essentially.

Once running, the controller works fine in FL. Also, it works without any start-up issue in Ableton, Cubase and Reaper.

I wonder what's causing this, and is there any way to stop FL detecting unused MIDI controllers - i.e. MIDI controllers that are used in other applications but not FL Studio (I have an LPD8 which I use to control RME's TotalMix app, but not FL Studio)?
