At the moment I am trying to convert the hid report descriptor to see
wether there is a bug in the FreeBSD parser or the descriptor. I have
found only a windows tool which didn't really work, so I am searching
for a spec to do it myself (in perl). From what I've seen, this
shouldn't be too difficult.
how about posting descriptor here in hex form, i.e. the same form you
put it into bthidd.conf?

So far not. The information I got was from a Linux patch which just
assembles raw packets (probably gained by sniffing). When I have a text
version of the descriptor, I can tell you more about that.
If it isn't in that descriptor, I will look into producing an updated
descriptor, but from what I've seen, I'm not sure this will be easy.

The problem is, I have abolutely no idea how to implement a device, so
thats why I suggested a local socket. The problem with that is, that we
need some kind of "ad hoc" protocol to select which device to talk to
(as bthidd can have multiple connections at once, iirc). I am planning
on a simple linewise text-based thing, but I'm not completely sure on
that yet.
again, you do not really need a device. socket will do just fine.
local client(s) can connect to the bthidd and identify which hid
device it (they) will be taking to, i.e. tell hid device's bd_addr.
then client(s) simply sends hid reports to the bthidd via socket and
it will relay them the hid device via bluetooth.
thanks,
