Looking at the code I see that the native backend only registers 0x1112, so
everything is fine for the native backend.

OK, meanwhile I found out that I need a "real" modem in my system, my
mobiles are not sufficient. So I installed phonesim and started the modem
emulation, powered on the modem and set it online. After that I see 0x111f
(and 0x1103) in the list and my headset connects the HFP profile when
powered on.
But still, after connecting I am only able to use a2dp in pulseaudio, when
switching to HFP, pulse  complains that the profile is not connected.

Anything special I have to do in phonesim to make it work?
