title: launch app on usb device connection on android
body: <p>I've got 2 devices mk802(android device) and ACS122(rfid card reader). I'd like to develop small application that will do the stuff, but at first I'd like to ask if it is possible to automatically start application when I plug the reader to mk802. </p>
  
  <p>I can see in documentation to usbmanager there is ACTION_USB_ACCESSORY_ATTACHED. So can I crate some listener (intent?) which will recognize the device (ACS122) and if it is this, it will start my application?</p>
  
  <p>thanks</p>
