Goodix HTK32 (USB 27c6:5385, 27c6:5335, 27c6:5395)

Status: Working via a community driver fork.

Goodix HTK32 capacitive press-type fingerprint sensor (108 x 88 px). The same driver covers product IDs 5335, 5385, and 5395.

Hardware

Seen on Dell XPS 13 9305, Dell XPS 13 7390 2-in-1, and Dell XPS 15 9570.

What was broken

Upstream libfprint has no driver for these Goodix HTK32 sensors, so they are unrecognised. The small 108x88 captures are also too small for libfprint's standard minutiae matching.

What the fix does

Adds a driver that initialises the sensor via PSK exchange and a GTLS handshake, detects finger placement through FDT events, captures the encrypted images, and matches using SIFT-based keypoint analysis (via OpenCV) instead of the standard minutiae matcher, which the small captures are incompatible with.

Build and install

Integrates with libfprint v1.94.10. Extra dependencies: OpenCV 4 and OpenSSL 3.0+ on top of the usual libfprint build deps.

# see CREDITS for the driver repo
git clone https://github.com/AndyHazz/goodix53x5-libfprint
cd goodix53x5-libfprint
./install.sh                       # follow the prompted meson.build edit
meson setup builddir --prefix=/usr
sudo ninja -C builddir install
sudo ldconfig

Arch users can install the AUR package libfprint-goodix53x5 instead.

Then restart fprintd and enroll:

sudo pkill -9 -x fprintd
fprintd-list "$USER"
sudo fprintd-enroll "$USER"

PAM setup

Enable fprintd in your PAM stack: distro helper where there is one, otherwise auth sufficient pam_fprintd.so (never required). Per-distro steps: docs/BUILD.md.
