How do you use a usb keyboard in Animal Crossing City Folk?

Some keyboards work and some do not. My Micro Innovations wireless brand did not work but my Microsoft wireless keyboard works fine and makes letter writing a breeze! Just plug the USB connection of the keyboard to the USB port on the Wii to see if yours will work. Also, the F keys (F5, F6, F7 and F8) will trigger the emotions you have learned from the City Theater.
