Virtual usb keyboard doesn't work

Hi! I used https://code.google.com/p/vusb-for-arduino/ library for working with usb. Its photo of device (with Schematic) I used this code

include "UsbKeyboard.h"

void setup(){}
void loop()
{
 UsbKeyboard.update();
  UsbKeyboard.sendKeyStroke(KEY_R);
delay (1000);
}

Where is bug? Thanks.

Dunno - your code looks similar to the examples. Did you notice this comment in the readme?

NOTE: The code will NOW ONLY WORK WITH THE PCB DESIGN
NOT THE PROTOBOARD DESIGN.

If you haven’t already checked it, I suggest you focus on the hardware design to make sure your circuit is correct for this version of the library.

No. Is there any reason you can't investigate this yourself?
