Greetings, all.

I've noticed some slightly strange (but not really problematic) behaviour
with the mice connected to my NetBSD machine (Quadra 800, NetBSD 1.4
GENERIC kernel).

In my setup, I've got a KVM switcher box connected to that machine and my
MacOS machine, so that I can share my keyboard, mouse and monitor between
the two machines, just by flipping a switch.  The NetBSD machine only has
an additional 3-button mouse connected for use with X-windows.  It's not
on the MacOS machine because the driver control panel doesn't work with
some newer interface elements (like the drop-down menus attached to
buttons in a window).  The KVM switch is connected to one ADB port on the
Q800, and the 3-button mouse uses the other port. 

At boot-up, the KVM box is always switched to the Q800, with both the
keyboard and mouse plugged in.  It stays switched until the boot
sequence is complete.  The weirdness is shown below:

It seems to find the 3-button mouse *twice*.  Next time, it seems to find
the Apple mouse twice:

I had two failures booting into NetBSD around this time, but they might
have been due to other hardware changes I was making, and the ADB sections
succeeded each time.  MacOS boots always went fine.  After I'd shut
everything down, checked all my connections, and powered up, it all went
smoothly.

I know that having two mice on the same machine is a little unusual, but
it's not supposed to be problematic, since trackballs/mice/joysticks and
other pointing devices usually can co-exist peacefully.  Does anyone know
why this might be happening? 

Thanks in advance for your input.
