Hey Hendry,
the IDs are a property of the XINPUT extension and the xinput(1) tool can be
used to modify XINPUT properties. It's the tool of choice for XINPUT devices.
What you might think of is a modification of the kernel (evdev) devices, for
example USB, which are listed in /sys/bus/usb/devices, but these don't know
about the XINPUT.ID.
Regards,
Ingo
