I'm using a Logitech Mobile Freedom Headset with my iBook G4. I have
been using this device for some time now, but since a week or so I'm not
able to pair with my headset anymore.

Output of btsco:
# btsco -v 00:0D:44:32:D3:FF
btsco v0.4c
Device is 1:0
Error: Failed to connect to SDP server: Permission denied

What kind of authentication failure is this? And how can I solve this
issue?

My version of the bluez-tools is 2.18.
The awkward thing is, that I'm still able to pair with other headsets
(same model) and my headset is still able to pair with other computers
or mobile phones.

I'd be glad for any kind of pointers in the right direction.
