[Bluez-devel] btsco doesn't start

[Nicolas Montavont <montavont@clarinet.u-strasbg.fr>]

Dear Developers,

I just bought an Plantronics M2500 headset and I have problems to make 
it work in my linux box. I hope you can help me.

The problem is I can not start btsco. Here is the output when I try to 
start btsco :

Device is 2:0
Error: btsco open (2-0): No such device or address

Here are the details of my settings:

I have a bluetooth PCMCIA 3com card, version 3 (driver serial_cs and 
hci_uart), and a linux-2.6.9 kernel (with bluetooth support from this 
kernel), btsco from CVS (revision 1.4 when I load the module). Alsa 
driver (1.0.8) were compiled outised the kernel.

I also try with the linux-2.6.10 kernel with patch-2.6.10-mh3.gz from 
bluez, and I get the same.

Once I did hciconfig hci0 up and hciattach ttySx 3com, I can see my 
headseat :
hcitool scan gives me :

00:03:89:79:84:48       M2500 by Plantronics
(to have this result, I have to put the headset in connection mode.)

but hcitool info 00:03:89:79:84:48 gives me :

Requesting information ...
Can't create connection: Connection timed out

I have same outputs if I try sdptool (sdptool browse or cc...)

In the Readme file it is written
3. run the daemon (enter the passkey if it's the first time 'round)
         btsco bdaddress

How can I set the passkey ? I know I have a code (0000), when do I have 
to set up this code ?

Here are other details, as you suggest in readme file :

hciconfig -a :

Any help would be really appreciated. Thanks a lot...
