[fprint] Detect finger in sensor

[Ing. Alfredo Alarcon]

Hi everybody, i have a 400b digital persona sensor, when i used the sdk 
from digital persona (before they charged it) the identify function wait 
for a finger n milliseconds and then break the function and continue 
with the program, but here in the libfprint the identify function blocks 
the program waiting for a finger in the sensor, what can i do with this 
problem??

Cheers.
