(Expanding on my original post ...)

What I assume is going on is that Windows is looking to see where the
mouse is connected.  Although I don't have the details, there are a
fair number of places to check, including an inport mouse, two serial ports,
and a bus port.  There is a requirement to meet timeout limits when checking
for mouse presence, and apparently they are set fairly high for Windows
(higher than in the MS mouse.sys, I suspect).
