Just built btsco from CVS and I can confirm that it works with the
following hardware.

Hawking Technology HBTC1 USB adapter
Bluetrek G2 headset (volume controls and call button are also detected)

The only problem I have is that the sound from the Bluetrek's mic is
muffled and quiet even if I set Mic volume to 15. It seems to be some
sort of soft clipping issue because from volume 8 to 15 yelds little
change and it is still as quiet (but distorted) if I shout at it.

Performance of the G2's Mic is fine when it is paired with my mobile.

Is there anything I can do to tweak the sound quality or are the quality
issues work in progress ?

Many Thanks for getting me this far
Wayne

We could pace the outbound data better in btsco. I'm not sure there is
much else that could help. I'm not very familiar with the kernel layers
involved in sco.
