Hi bluez developers,
I'm not sure if this is the right forum. I'm probably in-between alsa-user,
bluez-user, kernel-user? But here goes anyway:-)
I just tried getting the Logitech HS01 bluetooth headset working on kernel
2.6.6 (debian unstable), using the ALSA driver from
http://www.dcs.gla.ac.uk/~jp/snd-bt-sco/
Anyone had success with getting a headset working?
I know this driver is a hack, but it would be cool to have skype working using
a headset under linux.

--- cut: long and windy story about my adventures ---
I think I managed to patch my kernel-source-2.6.6 successfully. After
modprobing the modules dmesg says:
Bluetooth: L2CAP ver 2.1
Bluetooth: L2CAP socket layer initialized
Bluetooth: RFCOMM ver 1.2
Bluetooth: RFCOMM socket layer initialized
Bluetooth: RFCOMM TTY layer initialized
Bluetooth: SCO (Voice Link) ver 0.3
Bluetooth: SCO socket layer initialized
Bluetooth: HCI USB driver ver 2.5
usbcore: registered new driver hci_usb
snd-bt-sco revision ??$
snd-bt-sco: snd-bt-scod thread starting
so far so good.
After a while I got this additional message:
hci_acldata_packet: hci0 ACL packet for unknown connection handle 1
here is a summary of what I did:
modprobe hci_usb
modprobe sco
invoke-rc.d bluez-utils restart
Here I turned on the headset in this special "reset/pairing mode" (don't know
the right name for it - but you hold down the button for 10 seconds).
hcitool scan
Scanning ...

So that was end of the game.
At this time hcitool con says:

But I've also had it say:

Using strace I get this:

This could be caused by missing device files in /dev/ maybe?
I have ALSA compiled statically into the kernel, here is what dmesg says:

Hi Marcel,
Thank you very much for the reply. I have included the information you
requested at the bottom. First a little more information that might help you
help me :-)
When I start the user space "btsco" program the headset goes "off the hook" -
I hear a beep, the led starts blinking three blinks at a time, and I can hear
some "static" noise (mostly silent but occasionally some lsb "clicks"). I take
this as a good sign since it was mentioned in the readme for the snd-bt-sco
package:
"There seems to be some unexplained noise that's noticeable when a program has
the device open but is not sending audio data. Instead of seeing all silence,
the driver is receiving the occasional non-zero byte. I've added a temporary
filter to eliminate this, but I'd really like to know what's causing it."
As I said earlier, the buttons on the headset works - I can disconnect and
change the volume (can be seen in alsamixer :-)
dmesg has lots of these messages. Sometimes the number following handle is not
zero but a "random" integer.
hci_scodata_packet: hci0 SCO packet for unknown connection handle 0
hci_scodata_packet: hci0 SCO packet for unknown connection handle 0
hci_scodata_packet: hci0 SCO packet for unknown connection handle 0
hci_scodata_packet: hci0 SCO packet for unknown connection handle 0
hci_scodata_packet: hci0 SCO packet for unknown connection handle 0
Besides adding the snd-bt-sco alsa driver to the kernel tree, I have patched
the hci_usb.c of the 2.6.6 kernel with this patch (which was meant for 2.6.4):
<patch>
--- linux-2.6.4-orig/drivers/bluetooth/hci_usb.c 2004-03-11 02:55:44
+++ linux-2.6.4/drivers/bluetooth/hci_usb.c 2004-03-13 23:52:27
@@ -851,7 +851,12 @@
#ifdef CONFIG_BT_HCIUSB_SCO
case USB_ENDPOINT_XFER_ISOC:
- if (ep->desc.wMaxPacketSize < size || a > 2)
+ /* Use only the 9 byte

+ Bluetooth 1.1 Part H:2, section 2.1 */
+ if (ep->desc.wMaxPacketSize != 9)
break;
size = ep->desc.wMaxPacketSize;
</patch>
One further note: I had to increment the magic numbers in sndmagic.h because
the ones in the patch was already used in kernel 2.6.6. I assume this isn't a
problem as I have compiled both kernel and the btsco program with these
numbers... but something else might need to be changed also?
After having "used" the headset and turned it off I have trouble getting it
online again (without rebooting Linux). After putting the headset in "pairing
mode" I can do "hcitool scan"
Scanning ...
00:0D:44:00:76:07 Logitech HS01
But it fails with one of two error messages when I try to setup a connection:
hcitool cc 00:0D:44:00:76:07
Can't create connection: Input/output error
or:
Can't create connection: Connection timed out
But still "hcitool con" shows no connections.
Any ideas/suggestions welcome,
BR Peter

At the moment the headset is not turned on (don't know if that makes a
difference). Also I noted that sometimes the headset will be master and
sometimes slave. Not sure what that means though:-)

Hi again,
Well, I figured out I didn't have the /dev/snd/* device files
So now it almost works. The headset seems connected. I can use alsamixer (and
the volume buttons on the headset changes the volume in the mixer window).
hciconfig shows data is flowing at a steady rate from the microphone:
hci0: Type: USB
BD Address: 00:0B:0D:20:79:21 ACL MTU: 339:4 SCO MTU: 64:0

TX bytes:3768 acl:151 sco:0 commands:47 errors:0
But no sound
I'll try some more.

Hi,
i have the Same Headset Produktnumer under The Volume Controll on the
inner side is:F-0179A
And it works great. No Scratch or so Kernel 2.6.9 and different versions
of bluez all work ok.
Maybe its important what bluetooth dongle you use.

This ("Logitech HS01") is the model mine identifies itself as, FWIW.
It's sold as a Logitech Mobile Bluetooth Headset (as distinct from the
"Pro" version currently on their site).
And yes, it is a little noisy around other equipment. I use it sitting
at my PC, where there is a speaker set, two full powerstrips of
equipment, an FM radio receiver, a fan (although not typically switched
on), and a wireless network in the house. It's still just about usable.

Michael,
I don't have any immediate ideas about this... I'm not sure we've had
anyone using the logitech.
I've updated http://bluetooth-alsa.sf.net with a bunch of things we
typically ask when people are having trouble.
