[fprint] Problem with libfprint on embedded system

[Andres Aguirre]

Try run the libfprint example with strace and see where it is looking for
libusb.so, then make symbolic links of your libusb.so to the path that the
example are looking for.
It will be great if you could send me matchings time in the TS-7260 when you
achieve to make it work.
regards
Andrés
