Fingerprint sensor

Fingerprint sensors are usually attached to USB and do not need a kernel driver. To test it is best to install the fprint_demo packages that usually installs the library libfprint that does all the work.

Before installing a PAM module to use it as a password, fprint_demo should proof that it works reliable.
