From the website Arduino | Elektronica Voor Jou i've downloaded the demo that should simulate a mouse cursor move with the arduino (from here: http://arduino.nl/wp-content/usbmousedemo.zip)
I've compiled the UsbMouseDemo.pde program and uploaded it to my Arduino.

But when I ground pin 12 nothing happens, and I think my mouse cursor should move about 5 pixels. Anyone knows why nothing is happening?

Thanks

Still can't figure this out.
I would greatly appreciate anyone who had luck with the library.

Did you build the shield as seen here:

Won't work without that.
