[Pkg-bluetooth-maintainers] Bug#819598: (no subject)

[Matthew Gabeler-Lee]

Addenda:

I meant #816865, not 816815

Upgrading bluez locally gets rid of the prior errors, but produces other
errors, and the mouse still doesn't work (at first, but keep reading)

I cleared the previous pairing and tried to re-pair, just to be "safe"

Mar 30 21:20:56 hostname bluetoothd[1421]: GATT service objects disabled
Mar 30 21:20:56 hostname kernel: [   36.700194] Bluetooth: SMP security
requested but not available

The last line repeats every ~15 *milliseconds* until it times out and
gives up.  That sounds like
https://bugzilla.kernel.org/show_bug.cgi?id=104011

Following the suggestion there (bluetoothctl power off / power on) I was
able to pair and use the mouse!

The kernel.org ticket suggests it will be temporarily broken again when
I reboot, and that the root cause of that is a udev rule causing the
bluetooth host to be brought up in "legacy mode".
