I think this means that your keyboard isn't recognized as a keyboard. When it would have been recognized correctly an AIIOB-Exception on index 72 cannot happen with this class ...
Ah, but it is..it is recognized as a keyboard AND two other devices. One of those other devices lists a few buttons, sleep, wake up, etc.. some that I can't even find on the keyboard! But the other device causes the index error.
Note that this keyboard has multimedia keys (play,stop,volume up/down, etc.) a scroll wheel, and many programmable keys (Go, Finance, My Sites, Community, Favourites, E-Mail, Shopping, Search, My Home, iTouch)
