awesome!  just now figured out for 3012 devices we have to add VID/PID
some thing like this
http://lkml.indiana.edu/hypermail/linux/kernel/1206.1/00062.html

Please send a public patch for this
for bluetooth you will want to send them to Marcel Holtmann and cc the
linux-bluetooth mailing list, maintainers of ath3k
and cc me to0.
i think you go to see the following maintainer too
Gustavo Padovan <gustavo <at> padovan.org>

pls let me know if you need any help
