No Pairing BT Headset Ericson HBH-610a

[Siggi]

Hello Group,

I tried several descriptions on the Ubuntu Forums with no success. For any 
reason i'm not able to pair my headset with my laptop.

I want to use my Ericson HBH-610a Headset in my Kubuntu Edgy Installation.

Fllowing software i have installed:
aptitude  search bluez
bluez-btsco
bluez-cups
bluez-hcidump
bluez-pcmcia-support 
bluez-pin 
bluez-utils                                                                     - 

This is my little script with i try to pair my laptop with my BT Headset:
#!/bin/bash

hciconfig hci0 revision:

I had also a hcidump running during the script, which shows me:
<snip>

Here my configs 
hcid.conf 

# HCId options
options {
        autoinit yes;
        security auto;
        pairing multi;
       pin_helper /usr/lib/kdebluetooth/kbluepin
}

# Default settings for HCI devices
device {
        name "%h-%d";
        class 0x100;
        iscan enable; pscan enable;
        lm accept;
        lp rswitch,hold,sniff,park;
}

rfcomm.conf
rfcomm0 {
        bind yes;
        device "BT-MAC"
        channel 1;
        comment "HBH-610a";
}

Any help is very appreciated ! ;o)

Thanks in advance.
