[fprint] UareU 4000B DigitalPersona image encrypted

[Kleyson de Sousa Rios]

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 ?
