<p>I'm trying to use libfprint with UareU 4000B DigitalPersona fingerprint readers running in a Ubuntu 16.04<br>
</p>
<p><br>
</p>
<p>I'm able to use fprint_demo and img_capture program to get a new image, but the image is encrypted.<br>
</p>
<p><br>
</p>
<p>Based on the libfprint documentation, it's supposed the driver be able to decrypt the image.<br>
</p>
<p><br>
</p>
<p>Is it necessary do any extra configuration ? Might I be missing something ?<br>
</p>
