Comment 85 for bug 285089

I've downloaded and un-tar the archive at:
http://people.freedesktop.org/~hadess/libfprint-0.3.0.tar.bz2
and i've saved the patch (post 78) with a console I entered into the folder with un-tarred libfprint (in my case cd ~/Downloaded/libfprint-0.3.0) from here I do this command:
patch -p1 < ~/Downloaded/libfprint-0.3.0-vfs101.patch
and then
autoreconf && ./configure && make
and after I've installed the missing dependence package (I don't remember what package sorry) and the make is done without error the last command:
sudo make install
but (in my case) the installing path was wrong (/usr/local/lib) and I had moved the file in right place (/etc/lib64 in my case too).
then now you can launch fprint_demo with super user perission (sudo fprint_demo) to enroll your fingers.
and tadaaa the fingerprint reader works! to enable it to login search in internet (I've a guide in Italian sorry btw the link is http://forum.ubuntu-it.org/index.php/topic,445352.msg3486515.html#msg3486515)

@Sergio Cerlesi: after few day the driver works well! no problem with login :)
