"SCO packet for unknown connection" trouble with Motorla H500 headset

Hello,

I'm trying to use a  Motorola H500 headset (SCO) on an ubuntu hardy
heron computer with
 - bluez-utils version 3.26-0ubuntu6.
 - linux 2.6.24-18-generic
 - my dell latitude integrated bluetooth;

$ lsusb
Bus 001 Device 008: ID 413c:8103 Dell Computer Corp. Wireless 350 Bluetooth

I followed instructions there http://wiki.bluez.org/wiki/HOWTO/AudioDevices
$ cat ~/.asoundrc
pcm.bluetooth {
   type bluetooth
   device 00:19:1F:33:7E:58
}

Then I associate the headset and try it
mplayer -ao alsa:device=bluetooth "/usr/share/example-content/ubuntu Sax.ogg"

However, it does not work (no sound), and syslog is flooded by
 thinbox kernel: [ 5830.621543] hci_scodata_packet: hci0 SCO packet
for unknown connection handle 46
messages

When I ctrl+c mplayer, I can hear a "biip"

Thus I have two problems
 - the headset is not working
 - syslog is flooded

What is the root of these problems ? What is their status ?

I read Jawya messages
http://sourceforge.net/mailarchive/message.php?msg_name=alpine.LNX.1.00.0806021644270.9709%40nge2.ngu.pk
and I'm not sure this is fixed in new kernel/bluez versions, is it the
case ?

I'll try to keep https://bugs.launchpad.net/ubuntu/+bug/39414 up to date.

Best regards,
