My additional usb keyboard has strange behaviour when using the windows key

view story

http://askubuntu.com – The usb keyboard that I have connected to my Dell E6430 running ubunthu 12.04 with gnome 3 does not open the activites overlay when i press the "windows key" on the usb keyboard. It works just fine when I use the laptop keyboard. I used ~$ sudo /lib/udev/keymap -i To find what the key code was and in both cases (laptop and external keyboard) it is leftmeta. But when I go and configure keyboard shortcuts the leftmeta on the laptop keyboard shows up as Mod2+Super L and from the external usb keyboard it is Favorites. (HowTos)
