Are you sure you got that name right?  finger hps_at_freebsd.org comes back
"no such user".  I'm sorry to hear that I need now to learn yet another
vcs, but I have to admit that if I must, well, Perforce is probably the
best candidate for being a good tool.  I just really dislike using a
non-free tool for a free project (yes, I know there's a loophole for the
FreeBSD project).

I am still having a miserable time trying to figure out the HID spec, and
Kai Wang deserves being nominated for Sainthood, for putting up with my
horde of stupid questions.  If anyone knows of a HID device which has a
published [HID report in hex, Parsed output, and comments on how it got
from one to the other] I would give nearly anything for such a thing
(anything I happen to have, which doesn't happen to include cash right
now).  Kai Wang's krepdump gives you the hexdump and parsed output of any
device in your system that gets plugged in, which is 2/3 of what I need,
and anyone who hasn't seen that tool, who does usb programming, is missing
a great tool.
