ubuntu jaunty bluetooth dongle not pairing

I am trying to pair a BT headset with BT USB dongle, bluetooth-wizard does not pair the BT headset.
Running this command "pactl load-module module-alsa-sink device=bluetooth"
says "Failure: Module initalization failed".
FYI I have defined bluetooth in ~/.asoundrc

Here is some more info:

I have ubuntu jaunty 9.04.

i have the default installed bluez modules. bluez, bluez-gnome, bluez-utils, bluez-alsa.

I have gone through the BluetoothSetup procedure from https://help.ubuntu.com/community/BluetoothSetup

I have bluetooth dongle connected to USB port.

bluetooth-wizard: detects device does not pair. Not just a BT headset, it does not pair any BT device. Even if the target BT device finds my-pc and try to pair, it fails.

What is the problem? Is btusb driver not proper? I suppose I need some patch. where Can I get the patch for this problem. i have searched ubuntu launchpad and there are similar threads and it says fixed and upstream etc. Where is the patch and how to apply the patch.

Please help.

If it is paired, I would like to test it with BT headset,

Thanks.
