--- Comment #1 from Tanu Kaskinen <tanuk at iki.fi> ---
The error message comes from bluez5_sco_acquire_cb(). The function first
creates a socket:

    sock = socket(PF_BLUETOOTH, SOCK_SEQPACKET, BTPROTO_SCO);

Then it associates the local bluetooth adapter's address with the socket:

    bind(sock, (struct sockaddr *) &addr, sizeof(addr))

These steps succeed, but when the socket is connected to the remote device,
that fails.

    err = connect(sock, (struct sockaddr *) &addr, sizeof(addr));

I don't know how to interpret the "Unsupported protocol" error. Does that mean
that the kernel thinks that this particular device doesn't support the SCO
protocol? How could that happen? Hints from the BlueZ developers would be
welcome (I'll try to get Luiz to comment).
