--- Comment #1 from Martin Pitt <martin.pitt at ubuntu.com> ---
Can you please explain this in some more detail?

Those would apply to different devices and different keys, so in which sense
should they behave the same?

So what are you trying to do there, and what is the original assignment from
the kernel? Do you mean you can't assign multiple scan codes to the same key
code for USB devices?

Thanks!
