this is most likely due to gnome setting the keyboard settings on the virtual
core keyboard (VCK) where they are overwritten by the device-specific
configuration on the first key press.

nope, the server waits for xkbcomp to finish, long before the first client
connects.

setting the keyboard without a device flag changes the VCK. 
On the first keypress of a device however this setting is overwritten by the
keyboard that is actually being used. If you hit a key before gnome sets the
keyboard layout, the phys.  keyboard's settings are already copied into the
VCK and thus gnome can overwrite them again. consecutive keypresses don't
overwrite it again, since the phys. keyboard doesn't change.

the correct solution here is to let gnome set the keyboard settings on each
physical device they apply to.

Cheers,
