Have you considered the fact that maybe you not using the
right interface? The legacy joystick interface (with all its warts like
"replaying" the button state, in-kernel scaling and defuzzing, etc.) is
not what I would think a good general-purpose data acquisition
interface.
FWIW evdev does provide access to serial numbers (EVIOCGUNIQ) but even
that in my opinion is not the proper interface, for the reasons I
mentioned in my previous email.
You need to work with guys at linux-iio@xxxxxxxxxxxxxxx (which stands
for Industrial I/O which is exactly what you are working with).
