[Bluez-devel] SCO for non-CSR based devices?

[Gerhard Killesreiter <gerhard@killesreiter.de>]

Hi there!

I've recently purchased a bluetooth headset and discovered that my 
bluetooth adapter (a pcmcia card, 
http://www.sphinx-elektronik.de/deutsch/bluetooth/picocard.htm) isn't 
supported by bluetooth-alsa as there is no SCO support for this type of 
device.

During my searches on the web I noticed a kernel patch that was recently 
posted to this list 
(http://article.gmane.org/gmane.linux.bluez.devel/7579). I had a look 
and indeed my card has the problem which is mentioned there, namely it 
displays SCO MTU: 64:0 (Complete output of hciconf -a is at the end of 
this mail).

Now my question is: Would this kernel patch potentially allow me to use 
my card with bluetooth-alsa? Or is the actual problem unrelated? I am 
willing to recompile my kernel and apply this patch or test others, but 
I am really no kernel hacker and so I'd appreciate some input.

Of course, I could simply go and buy a CSR based bluetooth adapter, but 
that's boring. ;)

Cheers,
    Gerhard
