Compatibility SONY BRH10

In my Sony Xperia Ultra few function keys can be used:
- The Cursor * *
- The Back button
- The * Home button *
function * not * with my Xperia Ultra.

On both bones Android 4.4 installed.

All drivers have been installed correctly and the app on both devices.

For the Sony Xperia Tablet Z2 is the SONY BRH10, in my view, but to good use
