Does anyone have any idea how I can supply enough info to resolve this?

Every morning I have to unplug/replug my USB dongle and then open the
BT settings an reconnect my mouse.  It's getting very old and tiring.

I'd be more than happy to supply whatever kind of debug info is
necessary to get to a resolution on this.

My previous USB BT dongle did not have this problem at all.  But it
also didn't have BLE support which I now need.

Is btmon output useful here or some kind of driver or userspace debug
enabled, etc.

Any ideas?

Cheers,
b.
