I apologize for taking so long to reply. I have reinstalled the newer
version of libmtp-runtime (1.1.3-x) and I confirm that now firmware to
the atheros bluetooth is loaded correctly.
I haven't tried any new firmware (in fact, as far asI know the
firmware patch never made into Debian). This is with current stock
wheezy kernel and firmware.
I think this bug can be closed.
