Public bug reported:
When I connect my bluetooth mouse, the bluetooth indicator shows a
connection immediately, but the mouse is not responsive for another
10-15 seconds, at which point journalctl shows the following (it doesn't
show anything when the bluetooth connection is established):
```
May 02 07:12:35 taplop kernel: input: MX Master 2S as
/devices/virtual/misc/uhid/0005:046D:B019.0220/input/input424
May 02 07:12:35 taplop kernel: logitech-hidpp-device 0005:046D:B019.0220:
input,hidraw10: BLUETOOTH HID v0.06 Keyboard [MX Master 2S] on 9c:b6:d0:90:74:7a
May 02 07:12:40 taplop systemd-logind[7331]: Watching system buttons on
/dev/input/event26 (MX Master 2S)
```
In this case the bluetooth connection was established at 07:12:30, the
mouse started working at :40 and all 3 log lines did not show up in
`journalctl -f` until :40 despite the :35 timestamps (maybe just output
buffering though)
On the other hand, bluetooth headphones appear to be usable more or less
as soon as the connection is established, fwiw.
