Hi,
I've a really enerving problem.

On my desktop I'm not able to pair my headset without 
deleting /etc/bluetooth/link_key. After deleting the link_key
the pinhelper pops up and asks for the pin. I insert them and 
I'm able to connect.

My bluetooth dongle is from allnet and is attached to the usb port of a 
nforce2 mobo.

I allready submitted a bug report at the kde bugtracker cause I thought 
this is a kdebluetooth problem. Please look at   
http://bugs.kde.org/show_bug.cgi?id=104876 which could also be usefull 
information.

I tried all versions of bluez-utils and bluez-libs from 2.7 till 2.16 
and kdebluetooth from 20041107 till 0.99_beta1 in nearly every combination but 
everytime the same problem.

Curious is that on my thinkpad (T41p) evertime I pair my headset with the 
buildtin bluetooth module I'm asked for the PIN.

I'm really stumped. Please help me.

Regards 

Ruben
