Hi Nathanael and Lars,

Thanks a lot for these clarifications... I succeed to establish the 
connection through btsco.
I finaly use the alsa modules in the kernel and make the  modification 
to hcid.conf.

While it worked with aplay, it didn't work with gnomemeeting and then I 
tried to disconnect and reconnect. Now, I always get the following 
message, even after rebooting :

Can't connect RFCOMM channel: Permission denied

If I try sdptool --search ... it gives me the same output (Permission 
denied).

I get this either if I put the headset in pairing mode or not.

I am sorry to ask these questions, I am not really familiar with this 
equipment...

Thanks again !

Nicolas
