the CreateDevice needs some more magic in case the remote device has no
public browse group.

Currently we have in device.c the following struct:

static uint16_t uuid_list[] = {
        PUBLIC_BROWSE_GROUP,
        HID_SVCLASS_ID,
        GENERIC_AUDIO_SVCLASS_ID,
        ADVANCED_AUDIO_SVCLASS_ID,
        AV_REMOTE_SVCLASS_ID,
        0
};

So in case the public browse group fails, it will go through the list of
additional UUIDs and search for them. So your AVRCP case should be
handled.

So DiscoverServices will update the UUID list of course, but normally
there should be no need to call it. CreateDevice needs to be fixed to do
the right job.

The DiscoverServices is mainly for applications that need access to the
full service record. Stuff like obex-data-server for example.

Yep. We are almost done with. However you will need kernel changes to
make this work.

I wanna do the release actually today.
