Headset fails to reconnect input 1st connection after pairing

[Bastien Nocera <hadess@hadess.net>]

Hey,

I'm trying to connect an old Bluetooth headset to my desktop machine,
and it only manages to connect and create the input device to proxy
button presses when I first connect to the device, after pairing with
it.

The device is a Sony DR-BT21G (yes, ancient enough that behind the neck
headphones were still in fashion), the adapter is an Intel something
something (USB 8087:0a2b, lsusb just says "Intel Corp."), kernel is the
just released 4.13, bluez is git master (plus my battery patches).

This is the init for the adapter:

Info about the device:

This is the journal when trying to connect a second time. I don't know
what handle 0 is supposed to be but I'm guessing it's pretty important
because I haven't been able to get any sound out of the device
(PulseAudio is also the just released 11.0, but that's another
problem).

When pairing I don't see the error about handle 257, and the input
proxy is created. When it fails, it isn't.

                                       If you believe that dbus-daemon should be allowed read write access on the socket socket by default.
                                       Then you should report this as a bug.
                                       You can generate a local policy module to allow this access.
                                       Do
                                       allow this access for now by executing:
                                       # ausearch -c 'dbus-daemon' --raw | audit2allow -M my-dbusdaemon
                                       # semodule -X 300 -i my-dbusdaemon.pp
