Hello,
I have issues using "voice"/HSP/HFP profiles with this headset and
latest kernels/bluez cvs.
It seems it tries to use extended SCO when it shouldn't...
hcitool info xx:xx:xx:xx:xx:xx
Requesting information ...
BD Address: xx:xx:xx:xx:xx:xx

An other headset which support eSCO, works fine :

What can I do to help now ?

If it can help, I noticed there are a lot of these messages in syslog :
Jan 26 07:52:05 littletux kernel: hci_scodata_packet: hci0 SCO packet
for unknown connection handle 1
And with "hifi" profile, the headset playback works although it seems to
use eSCO too :
hcitool con
Connections:
> ACL xx:xx:xx:xx:xx:xx handle 11 state 1 lm SLAVE AUTH ENCRYPT SECURE
< eSCO xx:xx:xx:xx:xx:xx handle 0 state 8 lm SLAVE
I'm not sure what the problem is anymore...
Best regards,
Guillaume B.
