Reading Serial with Chrome App

I'm trying to get an Serial connection with a chrome app. I can connect to a device and send out data without a problem but cannot receive anything.

var onReceiveCallback = function(info) {
  if (info.connectionId == expectedConnectionId && info.data) {
    var str = convertArrayBufferToString(info.data);
    if (str.charAt(str.length-1) === '\n') {
      stringReceived += str.substring(0, str.length-1);
      onLineReceived(stringReceived);
      stringReceived = '';
    } else {
      stringReceived += str;
    }  
  }
  setStatus('Recieved');
};
chrome.serial.onReceive.addListener(onReceiveCallback);

I am using the chrome serial library and copied the example code from the website.

Have a look at https://github.com/GoogleChrome/chrome-app-samples/blob/master/samples/serial/espruino/main.js for a complete implementation of chrome.serial.

You may also want to check for errors with chrome.serial.onReceiveError.addListener(onReceiveErrorCallback);
