external keyboard configuration (yubikey)

[BRINER Cédric <cedric briner unige ch>]

Hi,

I do use a yubikey, which behave as a classical keyboard. But as I'm 
using a layout for my main keyboard which is not compatible with the 
yubikey. So each time I want to use my yubikey, I have to switch my 
layout from bépo (which is a french dvorak) to a swiss-french layout. Is 
it a way to assign in gnome-shell that this particular keyboard must use 
a specific layout as the swiss-french ?

Thanks in advance.
