title: Low-level USB API on Android at NDK level to use on Qt Android
body: <p>I need to interact with an HID device on Android. The problem is that i'm using Qt Android, and i'm not using Java UsbManager classes. </p>
  
  <p>Is there any C lib which I can link against in order to communicate with an HID device on Android without having to work with the Java API?</p>
  
  <p>I have found this:</p>
  
  <p><a href="http://source.android.com/devices/reference/bt__hh_8h_source.html" rel="nofollow">http://source.android.com/devices/reference/bt__hh_8h_source.html</a></p>
  
  <p>Which seems to be an header that defines HID communication but I can't find the associated lib. Any ideas?</p>
  
  <p>Thanks in advance</p>
