What is the input for 'game' and 'demo' example project?

Hi,

I am running some StarterWare example projects on OMAP L138LCDK board. The VGA monitor can show pictures of these two projects while I do not find any input (mouse or keyboard) works on the USB port. Are these projects complete or not? The mouse and keyboard do not have their LED light when connected to the USB port. I only see the following link mentioning the game project.

Anybody can talk more about these examples?

Thanks,
