Android not recognising midi devices over USB

Hi,

I try to write an android app that controlls hardware synths over USB with midi messages and I have a trouble recognising any midi device.

After lots of debugging I found this example witch can show the connected devices and it works on windows but on android It doesn’t see anything. (I set the minimum SDK version to 23 in the android exporter)
https://docs.juce.com/master/tutorial_handling_midi_events.html

Also I tried other apps if the problem is with the hardware but it recoginses the device with others. I tested on this for example:

So my question is, is It possible I found a bug in Juce, or I just messing up something?

I’m testing on Android 11.
