Hi, Daniel

I have two questions:

1. Maybe it will be better if libfprint will support different storages 
directly? Is there any special reason to move this functionality to the 
fprintd?

2. Is there any docs for async API? If I understand correctly, user of async 
API should use following scheme, am I right?

fp_async_open_dev();
fp_get_pollfds();

//setup timeout, struct pollfd, etc

//identify will call callback passed to it, this callback will
//set need_again to 0

need_again = 1;
fp_async_identify_start();

again:
ret = poll();
if (ret > 0) {
        fp_handle_events();
}

//do some app-specific stuff here

if (want_stop) fp_async_identify_stop();
if (need_again) goto again; 

fp_async_close_dev();
