Make sure you have sco support in your kernel, as a module or compiled 
in. Don't forget to load the module..

FYI: I have my share of trouble with SCO audio links so I have no clue 
what else you can do :)

Can you provide the part showing the Add SCO connection command?
You might have to try different packet types.

Best Regards,

Mayank

Sorry for stupid question.
Part of what you want to see?
Problem in function sco_connect of btsco.c:
 static int sco_connect(bdaddr_t * src, bdaddr_t * dst, uint16_t * handle,
                       uint16_t * mtu)
{
        struct sockaddr_sco addr;
        struct sco_conninfo conn;
        struct sco_options opts;
        int s;
        unsigned int size;

        if ((s = socket(PF_BLUETOOTH, SOCK_SEQPACKET, BTPROTO_SCO)) < 0) {
                return -1;
        }

        memset(&addr, 0, sizeof(addr));
        addr.sco_family = AF_BLUETOOTH;
        bacpy(&addr.sco_bdaddr, src);
        if (bind(s, (struct sockaddr *)&addr, sizeof(addr)) < 0) {
                close(s);
                return -1;
        }

        memset(&addr, 0, sizeof(addr));
        addr.sco_family = AF_BLUETOOTH;
        bacpy(&addr.sco_bdaddr, dst);
        if (connect(s, (struct sockaddr *)&addr, sizeof(addr)) < 0) {
                close(s);
                return -1;
        }

It's strange for me that SCO MTU is 0:0
I've tried to change it but its didn't help.

Tell me please what information do you need.
Thanks.

Actually, I wanted to see Add SCO connection command on hcidump.
Not the source code! Just wanted to see what packet types are going
in the command.

Correct. Your PDA does not support SCO links. See my previous mail.
It is simply not possible to change the features of a bluetooth device.

Ok. I have one stupid question.
My BT CF card doesn't support SCO.
Does this means that it dosn't support a2dp?
I tried start on PDA a2play and on notebook a2recv.
It's work.
I have plan to buy BT stereo headset to listen music from PDA...

No, since a2dp uses ACL link for transmitting stereo data.
A2dp has nothing to do with SCO.

It took me a while to understand this confusing situation.

The reason for this behaviour is very simple.
Have a look at the Features of your device: 0xbf 0x00 0x20 0x00 0x00
0x00 0x00 0x00
Here, byte 0 is 0xbf, byte 1 is 0x00. If you decode these numbers from
the bluetooth specs, bit 3 of byte 1 stands for SCO link. In your case
it is 0 which means your device does not support SCO links at all. Get
yourself a new dongle :(
Now you would ask me why does the packet type shows HV1? This is because
HV1 is mandatory if the device supports SCO link. So this is just a
mistake done by hciconfig. It should report HV1 packet type only if SCO
link bit is 1. In case it is 0 do not mention HV1.

Hope this helps.

Best Regards,

Mayank

Re: [Bluez-devel] btsco: Operation not supported

I have the same problem with bluez-utils 3.7
Then I compile version 3.9.
I think that problem in hcid.
I can stop it only by kill -9

I have Socket CF BT card on PDA. I'll try to find information is it support SCO.
Thanks

One moment. To compile snd-bt-sco modules I need to choose snd-hwdep
But it doesn't appear on ARM arch. I changed sound/arm/Kconfig adding "select SND_HWDEP"
