Subject: [Bluez-users] authentication problem when pairing with headset

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:

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.

in general yes, but I never tried it. However using TCP/IP over BNEP
directly should be enough.

Did you use it with the same dongle on another machine or OS?

This looks like wrong linkkeys. See the btsco page:

Ups - I see there is an error in there. [headsetaddr] should be
[dongleaddr]. The headsetaddr is in the linkkeys file on the line with
the linkkey. It is enough to remove that single line, thus retaining
the other pairing information.

Yes. sounds perfectly like this problem.
