Thanks, Peter!
However, I wonder if the attached patch to xf86-input-evdev might be
appropriate.
...or if it would be more appropriate for me to change something in
the kernel driver.... :-)
Peace,

Device must have buttons to be configured as a mouse.
In commit 71e9a69ed68257e5ded26c062a9797de571bb880 (2009-Apr-29)
has_axes was split into has_rel_axes and has_abs_axes... and this
resulted in the following change:
- if (has_axes && num_buttons) {
+ if (has_rel_axes || has_abs_axes || num_buttons) {
The result is that a device which only has axes (no buttons) will be
configured as a mouse. This patch requires that the device have at
least one button in order to be configured as a mouse.
This behavior was discovered when the Hercules DJ Console's MIDI port
was being configured as a mouse. This made the mouse unusable in X11
because the MIDI port is constantly sending events that are
interpreted as (0, 0) coordinates.
