Re: [Bluez-users] What's status of bt headset on linux?

[Robert Brewer <rwb123@gmail.com>]

I have the zonet usb adapter and a Logitech Mobile freedom headset.
btsco is needed, but bluez does not support broadcom chipsets
for SCO right now.  So it will not work.  With my setup I have gotten
btsco running, and I can ring the headset, but when the headset
answers, I get no audio.

I have tested the headset under WinXP with the same hardware
and it works fine.  So I am currently attempting to find out what
is needed to make broadcom chips work with SCO under bluez.
At this point I have sniffed some USB messages under WinXP,
my next step is to sniff the messaging under Linux and=20
then attempt to compare them.

Please write me off-list if you are interested in helping.
