title: Error: OSCOKIRQ failed to assert
body: <p>I'm trying to start a connection from my Arduino Mega ADK to my Android but I keep getting the error below whenever I try to acc.powerOn()</p>
  
  <p>Error: OSCOKIRQ failed to assert</p>
  
  <p>This is the firmware that I'm trying to run:</p>
  
  <pre><code>#include &lt;Wire.h&gt;
  #include &lt;Servo.h&gt;
  
  #include &lt;Max3421e.h&gt;
  #include &lt;Usb.h&gt;

  int led = 13;
  
  int EnableMotors = 22;
  
  int Motor1FW = 24;
  int Motor1RW = 26;
  
  int Motor2FW = 28;
  int Motor2RW = 30;
  
  
  AndroidAccessory acc("FRBB",
               "UgvBr",
               "DemoKit Arduino Board",
               "1.0",
               "http://www.android.com",
               "0000000012345678");
  
  
  
  // the setup routine runs once when you press reset:
  void setup() {
  
    // Setting Serial at 115200 bps
    Serial.begin(115200);
  
    // initialize the digital pin as an output.
    pinMode(led, OUTPUT);
  
    // Set up motor configs
    pinMode(EnableMotors, OUTPUT);
    pinMode(Motor1FW, OUTPUT);
    pinMode(Motor1RW, OUTPUT);
    pinMode(Motor2FW, OUTPUT);
    pinMode(Motor2RW, OUTPUT);
  
    // Powering the accessory
    acc.powerOn();             ///// &lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt; ERROR
  
  }
  
  // the loop routine runs over and over again forever:
  void loop() {
  
    if(acc.isConnected()){
  
      digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
      digitalWrite(EnableMotors, HIGH);
      digitalWrite(Motor1FW, HIGH);
      digitalWrite(Motor2FW, HIGH);
  
      delay(2000);
  
      digitalWrite(led, LOW);   // turn the LED on (HIGH is the voltage level)
      digitalWrite(EnableMotors, LOW);
      digitalWrite(Motor1FW, LOW);

      delay(2000);
    }
  
  }

  <p>I've been looking everywhere and I couldn't find a solution to this problem yet. I also tried the DemoKit with Arduino.app on 1.0.1, but still the same issue. I'm developing it using Mac, but I don't think that it is a problem.</p>
  
  <p>For testing purposes, I uploaded a code to blink the LED, and it worked just fine.</p>
