LibWiiKeyboard issue

I'm having trouble getting the libwiikeyboard example to work. I entered the code under "alternate usage" over at [wiibrew.org] and it compiles and runs okay. I get the "Hello World!" message and the "keyboard initialized" message but pressing keys does nothing. The lights on the keyboard don't light up, either. I've tested the keyboard on a PC so I know it works. Any ideas what I'm doing wrong?

Never mind. Figured it out. :)

What's the solution you found?
Sharing it may help the comunity. I found this problem also, all I did to fix it was reload another specific IOS, can't remember wich one right now.
