Bluetooth mouse connects, but does nothing else

Hello everyone,

I have recently installed debian with KDE, and my pc connects properly to my bt mouse (sometimes with the help of bluetoothctl), that does get recognized as input device, when connecting nothing happens!
I can confirm that the problem is neither the mouse itself (it works on both windows and my android device) nor the bluetooth stack on my laptop (my bt earphones connect and stream audio properly).

I’ll paste the bluetoothctl output when i try to connect AND to disconnect after trying the mouse, maybe this helps.

roberto@debian:~$ bluetoothctl
