I'm running Ubuntu Hardy, so I have a nice bleeding edge installation of
kernel and bluez tools. I am trying to get a Jabra headset to work but
it's just not happening for me. I plug in the dongle and get the little
bluetooth applet showing in my taskbar. My headset also beeps when this
happens.

I believe it's all paired up nicely:

I follow the steps in http://wiki.bluez.org/wiki/HOWTO/AudioDevices but
when I try to play something with:

Anyone got any advise?

the patch you sent me is fully broken. First of all the coding style
is wrong. Does nobody have learned this by now? I always look for that
first before even reading the patch. Second the case where an
ESCO_LINK returns NULL is broken and will fall over and crash.

Marcel

Is this something that can go upstream easily?

I tend to avoid patching and building kernels since I tend to follow a
distribution's development version (i.e. currently Ubuntu Hardy) which
means high kernel turnover, which means I spend too much time patching
and building kernels if I maintain a patch (series) outside of the
vendor's kernel.
Perhaps I can convince Ubuntu to roll this patch in. If it's hoped to
be accepted upstream that might be possible. If it's been rejected
upstream for whatever reason, Ubuntu probably won't let it in either.

How do I determine if this is the case? Just to see if we are barking
up the right tree?
Thanx!

I've added the kernel patch that is supposed to handle this problem to
the end of the wiki page. Please let us know if it helps. It's
ostensibly going to be an issue if you have a bluetooth adapter
capable of esco but your headset is not.
