Bluetooth adapter not listed in linux-3.14.2

Bluetooth adapter not listed in linux-3.14.2

[Sree Harsha Totakura]

Hi,

I am running linux-3.14.2 and currently issues with bluetooth where my
bluetooth card is not listed.  From the kernel I found this output which
I guess is relevant here.

I forgot to mention that the file `intel/ibt-hw-37.7.bseq' is present is
/lib/firmware.
