Bluetooth keyboard disconnects randomly after hid2hci installation

I used to work with a bluetooth mouse and keyboard with no inconveniences, until the mouse click broke, so I had to replace it with another mouse.

The mouse I acquired apparently works only with the bluez-hid2hci package installed, sincerely I don't even know why, but I noticed it after trial and error. Since then the keyboard disconnects and reconnects randomly, which is indeed very frustrating

Here a capture of the relevant journalctl logs (bluetooth debug mode is enabled):

Re: Bluetooth keyboard disconnects randomly after hid2hci installation

any help? I think that probably setting the mode per-device could help, but I don't know how
