Mouse takes a long time to "wake up" after overnight absence

["Brian J. Murrell" <brian@xxxxxxxxxxxxxxx>]

On my machine with Bluez 5.72 I have replaced my old BT dongle with a:

Bus 003 Device 029: ID 0bda:8771 Realtek Semiconductor Corp. [unknown]

I have a:

	Name: Bluetooth Mouse M557
	Alias: Bluetooth Mouse M557
	Class: 0x00000580 (1408)
	Icon: input-mouse
	Paired: yes
	Bonded: yes
	Trusted: yes
	Blocked: no
	Connected: yes
	WakeAllowed: yes
	LegacyPairing: no
	UUID: Service Discovery Serve.. (00001000-0000-1000-8000-00805f9b34fb)
	UUID: Human Interface Device... (00001124-0000-1000-8000-00805f9b34fb)
	UUID: PnP Information           (00001200-0000-1000-8000-00805f9b34fb)
	Modalias: usb:v046DpB010d1001

paired to it.

If I leave the computer briefly (minutes, perhaps even a small number
of hours) and return the mouse continues to work correctly.

If I leave the computer for a longer period of time, like say, over
night until the next day, when I try to use the mouse it does not work
immediately.  I can take a few tens of minutes for it to "wake up" and
be functional again.

I didn't have this problem with my old BT dongle.

Any ideas how to resolve this?
