vfs495-driver: a Linux driver from fingerprint-reader protocol research

vfs495-driver implements a Linux libfprint TOD driver for the Validity VFS495 swipe fingerprint reader. Its documented research traces the sensor's USB handshake, encrypted command and image streams, and firmware patch setup; a build recipe extracts required command data from the user's HP SoftPaq download.

Requirements & limits

Prerequisites: A Validity VFS495 reader with USB ID 138a:003f and libfprint with TOD support are required.
Prerequisites: The build downloads HP SoftPaq sp84530 to extract setup commands and firmware patches; the repository does not contain that data.
Testing evidence: The author reports testing on one HP ZBook 17 G3 with Ubuntu 25.10 and 26.04; other sensor variants may need different patches.
