title: How to communicate with a USB device from Android tablet?
body: <p>From a year ago, <a href="https://stackoverflow.com/questions/2815518">Is there a way to communicate with USB devices on Android?</a> this didn't look like a common requirement, but tablets have evolved, and hopefully, the OS has, as well.<br>
  I need to operate a simple USB relay card from my Curtis LT8025 tablet, currently running 2.1 patched.<br>
  I'm also a newcomer to both Android and java, so relatively clueless!<br>
  No need for bi-directional communication, just a simple serial command out to the device.  </p>
  
  <p>Any suggestions?</p>
  
  <p>Thanks!<br>
