Hello!
I am having problems using the device node created for the bluetooth
device (rfcomm0) with the error "connection refused". Notable is that I
have successfully set up same kind of connection with same type of
configuration
System: Archlinux
Kernel: custom kernel 2.6.13-mm2, tried various others down to 2.6.10
Userspace: bluez-utils 2.20-1
Bluetooth devices on laptop: Built in acting as a bluetooth usb dongle
and an actual Dlink USB dongle. Same result.
Starting of services:
Frixy ~ # /etc/init.d/bluetooth start
Starting Bluetooth subsystem: hcid sdpd hidd hid2hci rfcomm pand.
System logs:

Any application trying to use the device node fails. Pin code is
verified because I get "Access Denied" if wrong pin code is entered
before the devices are paired. The devices are successfully paired.

I have tried all possible configuration options in the phone as I can
think of. Since I've used 2 other cell phones as GPRS/UMTS modems before
(A nokia and a sony ericsson) I have played around with most common
settings as can be done.
I have followed guides and tried to find one single case of any user
having the same problem as I without success.
I am suspecting that some of the devices dosent follow the standards in
communication protocol. The tricky question is to find out where and
what goes wrong. :)
Any help is appreciated. Thanks!
Mikael
