Hi Max,

I followed this sequence. One thing to note is that the mouse tries it's
best to conserve power, so it only responds to any initial queries for a
few seconds after pressing the reset button. I don't know exactly how
long, but it's pretty short. Klausler makes a note of this on his site,
so it must have caused him a hiccup or two.
> please send me the output of hcidump.
Okay, here it is. Turns out I think my batteries ran out of juice, which
was causing some of the problems. I wasn't getting any response at all
after all sorts of resets so I tried seeing if I could find the keyboard
and it 'just worked'. I replaced the batteries and got a response from
hccontrol inquiry. Just in case replacing the batteries turned out to
reset it more than pressing the button I put the old batteries back in and
still got nothing. When the batteries 'die' the mouse still lights up
(it's optical), and apparently the radio connection goes first. Anyway,
without further adue here is the hcidump output:

These give a lot more help than the man page.
I managed to get 'remote_name_request' to return 'Microsoft Mouse'
(yippee!), but I just arbitrarily chose <ps_rep_mode> and <ps_mode> as 0.
I used 'read_clock_offset' to get the clock offset. What are these 2
options and how would I properly find them?

I'll start CC'ing this to freebsd-current starting with this message.
Thanks,
