To get it work you need:
- patch from review
- my patch in comments, it must be applied against current src tree 
after previous patch.
- updated firmware from comms/iwmbt-firmware (allready in ports tree 
since 124f62b82791b7fe8056f58c6455b77f107e1e6d 
<https://cgit.freebsd.org/ports/commit/comms/iwmbt-firmware?id=124f62b82791b7fe8056f58c6455b77f107e1e6d>)

This partialy works on my laptop - obex is ok, but bluetooth mouse via 
bthidd do not works.
