I'm getting beyond my depth, Paul. I thank you very much for all your
research, but I'm not sure I can do everything you suggest or whether I'm
capable of ever fixing the problem. Here's what I've found so far:

* I did a search on Apfiltr.inf in the Windows\inf folder and found
nothing.
I then searched on just Apfiltr in the Windows folder (not just the inf
subfolder) and found only Apfiltr.sys in Windows\system32\drivers.

* I checked the Properties of the Dell Touchpad again and found that for
both the working and the nonworking port, at Touchpad External Mouse
Settings | Hardware, the Dell Touchpad location is "plugged into PS/2
mouse
port." On the working port, the Perfit Mouse (USB) is at location 0; on
the
nonworking port, the mouse is called an HID-compliant mouse manufactured
by
Microsoft, and it too is at location 0.

* When I looked at the Driver File Details for the Contour Mouse in the
good
port, there were several files in Windows\Contour and two in
Windows\System32\drivers. The two driver files are hidxmse.sys and
mouclass.sys. The one that's checkmarked is mouclass.sys. On the bad
port,
the Driver File Details for the HID-compliant mouse are
Windows\System32\drivers\mouclass.sys and mouhid.sys.

Thank you for everything, Paul!

The last driver I could find reference to for the Contour Perfit, should
have been here, but is not archived. The last driver might have been
offered
around 2008 or so, and then removed from the Contour web site.

Would the download at the bottom of this page not work (the one for Contour
Mouse for WinXP, Vista, and Win7)?
