title: Send and Receive Data on USB Port via Android App
body: <p>I am trying to build an android app which will fetch some data from a URL and send it on the USB port of my android tablet. The USB port is connected to a USB-Serial Port Converter.</p>
  
  <p>I am not able to figure out the part where you send data on USB port.
  After lot of googling I found ADB, <a href="http://code.google.com/p/microbridge/" rel="nofollow">http://code.google.com/p/microbridge/</a> etc but none of them have a java library that can be used.</p>
  
  <p>Any suggestions?</p>
