Maudio keystation mini 32 (midi keyboard) not recongnized on Fedora

I tried to use my midi keyboard, a MAUDIO Keystation mini 32. The purpose is to use it with musescore.

I’m quite lost as the keyboard isn’t recognized at all, it even doesn’t appear when I try:
$ aconnect -i

the answer is:
client 0 : ‘System’ [type=noyau]
0 'Timer ’
1 'Announce ’
client 14 : ‘Midi Through’ [type=noyau]
0 ‘Midi Through Port-0’

The keyboard works well with Windows, and has worked fine with elementary OS for years

Thank you for any help!

A web search tells me that you seem to need to install the package midisport-firmware, have you?

See if things work after sudo dnf install midisport-firmware and a reboot.

Thank you! I should have mentionned it, it has been done and seems not to be enough…
I also installed QJackCtl, but of course the keyboard does not appear (as it is not even recongnized as a keyboard).
