Replying to an old email about a patch that hasn't made it yet (at least
to 2.6.17.3).
Without this patch I can't use my Belkin F8T012 with the bluetooth alsa
sound driver (snd-bt-sco)
with it, I can :)
Thanks Olivier.
Is this likely to be merged?
David
PS, I tried the patch here:
http://bluetooth-alsa.sourceforge.net/sco-mtu.patch
that is mentioned here:
http://bluetooth-alsa.sourceforge.net/
but it doesn't work for me.
