Hello, I've been trying to use my computer as "handsfree" with
"Hands-Free Profile" using "Intel Corporation Centrino Wireless-N
1030". I accept() the BTPROTO_SCO socket, but never recv() any
data. Your post looked similar!

When googling I found this:

http://www.netbsd.org/docs/guide/en/chap-bluetooth.html#chap-bluetooth-audio
    SCO Audio will not work with ehci(4) USB controllers, since support
    for Isochronous data over EHCI is missing in NetBSD.

Does Linux support this? (I have no idea what it means)

Hi Stevie,

Thanks for your input, I don't know the answer of your question, but at least the camera works well on the EHCI bus, and camera transfers the ISO packets over EHCI bus.

Regards,
Hui.

I'm sorry if this mail is somewhat broken. I could only find your email
on "gmane" and it had encrypted all your email addresses!

Hi Hui,

The attachment lenovo-k4450-btmon-v1.log is the log of intel 7260
init procedure + scan headset + connect headset + play sound.
I looked through the logs and the controller init is just fine. So
in theory this should route the SCO audio frames over HCI. For some
reason it does not and I have no idea why not.

That it makes a different between EHCI and XHCI is strange. I can
not explain this. Maybe Tedd can help you since I have no further
insights in our chips at this moment.
Thanks Marcel for your kind help and analysis.

Tedd, did you reproduce this issue on the machines with intel 7260 BT
module connected to the EHCI bus? Did you have any idea on this issue?
