A post-2.6.26 regression.

Distribution: Debian
Hardware Environment: Intel Core2 Duo CPU E6550
Software Environment: Debian unstable + bluez-4.4
Problem Description: my Jabra JX10 bluetooth works with 2.6.26-1-686 and bluez-4.4. With 2.6.27-rc5 (btusb) it only hisses.
Steps to reproduce: install bluez-4.4 http://www.bluez.org/ and add the following to ~/.asoundrc
pcm.JX10 {
        type bluetooth
        device "00:1A:45:2F:49:98" # Jabra JX10 series 2
}
as root run bluetoothd -dn
run aplay -D JX10 alarm.wav
with 2.6.26-1-686 I could hear the music, now I just hear a soft hiss during 40 seconds and then get an error message.
hcitool shows 2 connections during the 40 seconds:

yes. I read the change log for 2.6.27-rc6 and it doesn't seem to address my problem. Should I try it anyway?

I forgot to mention that my bluetooth dongle is a USB

Latest working kernel version: 2.6.26-1-686 (Debian) Earliest failing kernel version: 2.6.27-rc5 (vanilla)
A post-2.6.26 regression.

I just installed bluez-4.9 and linux 2.6.27-rc8 hoping that my Jabra JX10 bluetooth headset would start working. Still no luck. Bluetoothd says "connect: Operation not permitted (1)" and aplay "BT_SETCONFIGURATION failed".

I also downloaded the 2.6.26-mh6 patches from
http://www.bluez.org/more-usb-driver-fixes-and-quirks/ and recompiled another kernel. The kernel crashed twice (I only booted it twice) rather quickly. I did get time to run aplay once and it gave the same errors as shown here. The hcidump is almost exactly the same.

The Jabra JX10 "features Bluetooth 2.0 and e-SCO for improved audio quality and MultiPoint capability for connecting to 2 devices at once" and I am using an old Bluetooth 1.2 Linksys USBBT100 USB dongle. Could that be what is causing the problem?

I ran strace on bluetoothd and it appears that it is
"bind(25, {sa_family=AF_BLUETOOTH, sa_data="0\377\341A\f\0\310\261\v\270H\225d\271"...}, 8)" that is returning -1 with errno set to EADDRINUSE
