Please capture the raw reports
from /sys/kernel/debug/hid/0005:*:0306:*/events when pressing multiple
keys -- and tell me which ones they were. You may need to mount debugfs
to get to this path.

It looks like this simple approach isn't going to work when you press
multiple keys, so I'll need more information to see if I can do
something else -- my Harmony can only do one key press at a time, as it
is converting IR to an emulated BD remote.

Will do, thanks.

Will add something along these lines, though I think you mean there is
no authentication step rather than a NULL pin, which implies we still
need to do auth. Or maybe that's just how the Harmony needed it...

Thanks,
Dave
