Hi there,

 also seeking a solution for the Validity VFS451 Fingerprint Reader --
on a HP Probook 6540B:

$lsusb
Bus 001 Device 004: ID 138a:0007 Validity Sensors, Inc. VFS451
Fingerprint Reader

$lsb_release -a
Description:	Debian GNU/Linux 7.7 (wheezy)

The latest driver version from HP-SuSE, for the Probook 6540B, was also
released somewhere in the year 2011 and is an RPM build. However, I can
no longer find that specific release or any othoer. So I've since
contacted HP support and just awaiting some reply (URL).

... of course I won't hold my breath on that.

Because of my lacking of technical software engineering skills I'm
probably not of much assistance other than what others have already done
-- just locate the latest release of the closed source Linux binaries
and submit a URL to the source.

Sourcing MULTIPLE HP releases of closed source linux binaries for each
variant of their scanner hardware may prove a mission in itself.

I've read fprint's Project Needs(recommended reading):
