The good news: I just went and bought an additional BT dongle, nice and
CSR-based:

The bad news: Suddenly things work even less than before. I must have
badly fucked up my configuration along the way. I can't even talk to the
Headset now. hcitool scan works, nothing else, not even hcitool info:

sp8472@Maik-2013:~$ sudo /etc/init.d/bluez-utils stop
Stopping bluez-utils: rfcomm sdpd hcid.
sp8472@Maik-2013:~$ sudo /etc/init.d/bluez-utils start
Starting bluez-utils: hcid sdpd rfcomm.
sp8472@Maik-2013:~$ hcitool scan
Scanning ...

sp8472@Maik-2013:~$ sudo hcitool info 00:07:A4:C0:25:A5

Any idea how to get things working now?
