Hmmm...
/usr/src/lib/libusbhid/
Nope..
Aha...maybe this is it:
/usr/src/usr.sbin/usbd/
ll /usr/src/usr.sbin/usbd/
2734320 -rw-r--r-- 1 root wheel 169 Apr 25 2001 Makefile
2738254 -rw-r--r-- 1 root wheel 4460 Jun 22 2003 usbd.8
2736938 -rw-r--r-- 1 root wheel 30079 Nov 29 2003 usbd.c
2737339 -rw-r--r-- 1 root wheel 5046 Aug 27 2004 usbd.conf.5
Is that the one?
Here is a part of 'tail -25' on the file, showing the bottom:
/* check the event queue */
if (handle_events && (FD_ISSET(fd, &r) || error == 0))
{
if (verbose >= 2)
printf("%s: processing event queue
%son %s\n",
__progname,
(error? "":"due to timeout "),
USBDEV);
process_event_queue(fd);
}
}
}
So no, this file doesn't end in what you ask; I can't see anywhere
else it might live; is there some other usbd.c you need?

Ah...okay; well, I was in the dark anyway, may as well whistle.

Okay; it may be a one off, relative to me only, as I've seen no other
indications of issues. I am behind on my list reading, though.

Yes; once I have a console, the mouse is detected:
ums0: Logitech USB Receiver, rev 1.10/23.02, addr 2, iclass 3/1
ums0: 7 buttons and Z dir.
Then, it works in X just fine; I forgot to test it on the console.

I don't care what you think. This is not a stylishly insouciant stroll
out of the jungle, here. It's more like we've fallen out of our trees
and rolled, butt-naked before the entire galaxy, downhill. That, and
we seem to have a teensy problem lifting ourselves off the ground.
