Hi, I'm having some issues with my keyboard that I hope you can help me with. I have a standard Apple USB Keyboard attached to my Mac Pro. Yesterday I installed Mountain Lion and some Logitech drivers* for my G500 mouse, and now my keyboard is locked to an American layout. When I try to switch to a Norwegian layout, the option is greyed out (see attachment 01.jpg). I have tried the Keyboard Setup Assistant. It tells me to press the button on the right side of the left shift-button to identify the keyboard, but when I do, I get an error messag saying the keyboard couldn't be identified. The problem is only present after I have logged in, and everything works fine in the OS login-menu. Google wasn't any help. *The Logitech download installed some sort of unifying software and a Logitech Control Center in my system pref-pane. I have deleted both.
