# fpdrv: reconstructing Synaptics 06cb:00e7 fingerprint communication

> fpdrv reconstructs communication with the Synaptics 06cb:00e7 fingerprint sensor as a Linux userspace driver, libfprint TOD module and diagnostic CLI. It implements host pairing and a TLS-like encrypted session for on-chip enrollment and matching. Its protocol notes map USB endpoints and captured connection flows.
