Pressure Sensor HSCDRRN002NDAA5 (Honeywell) and Arduino YUN

Hello guys,
I work in a project with Pressure Sensor HSCDRRN002NDAA5 (Honeywell) and Arduino YUN but I can not get any information from the sensor, in resume I use:
Arduino board: Yun
Sensor: Honeywell HSCDRRN002NDAA5, Datasheet: http://www.mouser.com/ds/2/187/HSC%20Analog-221530.pdf
Software: Arduino 1.5.4
Port: COM17 (I've checked the port for my Arduino in 'device manager' option in Windows)
Library: SSC.h Arduino Playground - HoneywellTruStabilitySSC-HSCPressureSensors
Code, the basic one of the example:

#include <Wire.h>
#include <SSC.h>

//  create an SSC sensor with I2C address 0x78 and power pin 8.
SSC ssc(0x78, 8);

void setup() 
{
  Serial.begin(115200);
  Wire.begin();
 
  //  set min / max reading and pressure, see datasheet for the values for your 
  //  sensor
  ssc.setMinRaw(0);
  ssc.setMaxRaw(16383);
  ssc.setMinPressure(0.0);
  ssc.setMaxPressure(1.6);
 
  //  start the sensor
  Serial.print("start()\t\t");
  Serial.println(ssc.start());
} 

void loop() 
{
  //  update pressure / temperature
  Serial.print("update()\t");
  Serial.println(ssc.update());
  
  // print pressure
  Serial.print("pressure()\t");
  Serial.println(ssc.pressure());
  
  // print temperature
  Serial.print("temperature()\t");
  Serial.println(ssc.temperature());

  while(1) {
    // use Serial as a command stream
    while(Serial.available()) {
      ssc.commandRequest(Serial);
    } 
    delay(100);
  }
}

I connect the following port of the sensor to Arduino board:
Pin2 -> 5V
Pin3 -> Pin 8 of Arduino
Pin4 -> GND

I can blink my Arduino board then the problem (I suppose) is on the code.

Any advice?

Thanks.
