First, operator error; the xml was in /Input. Moving it to /Input/Event brings back the fatal exception.

Just two posts ago : " Both mouse and trackball do the same things."
and now: " since connecting the extra mouse."
And I know the tablet "was mentioned" but I said, get rid of it, in other words you should work stepwise: work to get a simple system operating as expected and move in steps towards to setup you want. i.e. Two devices, each a standard USB mouse with the event file that everyone else says works OK.
0) Put aside trackball, graphics tablet, uninstall any drivers for same
1) _____One____ input device, a USB mouse, no event file verify fgfs works and mouse cycles modes as documented .
2) Add a secind ______USB Mouse _____ not a tablet, not a trackball . Put the second mouse's product name into the event file from wiki/"Two Mice" thread and install just that in flightgear
3) First mouse should work as before, second mouse should operate ailerons / elevators , that's what everybody else sees.
One basic usb mouse, and FG works as expected. Two basic usb mice, and FG works as expected. Two basic usb mice with the xml, and still a fatal exception. Disconnecting the trackball and the tablet and using two basic usb mice had no effect. The trackball is not fancy nor does it have drivers. To the system it is a pointing input device and has no idea that a trackball surface is being moved over sensors, rather than sensors in a mouse being moved over a surface. The tablet also has no drivers other than Wayland which is preinstalled anyway.
Finally, help is appreciated, but if you are that frustrated, you are under no obligation.
You're in a desert, walking along in the sand, when all of a sudden you look down...
What one?
What?
What desert?
It doesn't make any difference what desert, it's completely hypothetical.
But, how come I'd be there?
Maybe you're fed up. Maybe you want to be by yourself. Who knows? You look down and see a tortoise, Leon. It's crawling toward you...
Tortoise? What's that?
You know what a turtle is?
Of course.
Same thing.
I've never seen a turtle. But I understand what you mean.
You reach down and you flip the tortoise over on its back, Leon.
Do you make up these questions, Mr. Holden? Or do they write 'em down for you?
The tortoise lays on its back, its belly baking in the hot sun, beating its legs trying to turn itself over, but it can't. Not without your help. But you're not helping.
What do you mean, I'm not helping?
I mean, you're not helping. Why is that, Leon?
