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