Hello Marcel,
As per your request i have pasted the result of
“hciconfig -a” and “hcidump -X -V”. Along with it
someother information which i thought might be helpful
in debugging.

When i first started my pc if found that hcid demon
was not running. So i re-started the bluetooth
services and made the hcid to run
-------------------------------------------------------
[root@localhost bluetooth]# /etc/init.d/bluetooth
status
hcid is stopped
sdpd (pid 1729) is running...
[root@localhost bluetooth]# /etc/init.d/bluetooth
restart
Stopping Bluetooth services:                          
    [FAILED]
Starting Bluetooth services:                          
    [  OK  ]
[root@localhost bluetooth]# /etc/init.d/bluetooth
restart
Stopping Bluetooth services:                          
    [  OK  ]
Starting Bluetooth services:                          
    [  OK  ]
-------------------------------------------------------

The headset is being put in the pairing mode. Hcidump
-X -V is running in the background. I execute the
btsco command
-------------------------------------------------------
[root@localhost /]# btsco 00:08:C6:3E:54:2C -v -r
