    Try Wire.setModule(0) before calling Wire.begin().
    Reason is that the standard changed for the wire pins from ping 14/15 to pin 9/10 a while back. You are better off using pins 14/15 on the G2553 though since Wire on pins 9/10 is a software implementation. So use Wire.setModule() before Wire.begin() to allocate Wire to the hardware supported I2C pins.
