I am using Ubuntu 20.04 LTS on my HP Envy x360. LSUSB detects the fingerprint scanner, but FPRINTD does not detect the hardware. Since LSUSB detected it, is there a chance I could get it to work?

phenom@PhenomFire:~$ lsusb

Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 004: ID 04f3:0c4c Elan Microelectronics Corp. ELAN:ARM-M4
Bus 003 Device 003: ID 0408:542a Quanta Computer, Inc. HP Wide Vision HD Camera
Bus 003 Device 002: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 003 Device 005: ID 8087:0026 Intel Corp. 
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The second device (04f3:0c4c Elan Microelectronics Corp. ELAN:ARM-M4) is the fingerprint scanner.

  • Can you [edit] your question to include the output of lsusb? Not every Envy x360 uses the same reader. Please note that detection does not always mean usable. The operating system may know that something exists but, without a driver that's able to interact with the hardware, it may not be able to use it. – matigo Jun 02 '21 at 01:26

    It appears that this device currently does not have Linux support. See also here and here. – Alex Hajnal Jun 02 '21 at 01:44
  • use this link https://fprint.freedesktop.org/supported-devices.html to verify if your device is supported by fprintd, if it is then try this sudo systemctl status fprintd.service and paste here the output. – adrian_vrn Nov 08 '21 at 11:12

The fingerprint sensor is currently unsupported in fprint. Here is a list of supported devices.

Try this:

For me I compiled and installed from the source. Make sure you have git installed.

sudo apt install libcairo2-dev meson ninja-build libgusb-dev  libgirepository1.0-dev libnss3-dev libgudev-1.0-dev gtk-doc-tools valgrind
sudo ldconfig
git clone https://gitlab.freedesktop.org/geodic/libfprint.git
cd libfprint/
git switch elanmoc2
git pull
meson build
cd build
ninja
sudo ninja install

Also after the build you could test the examples from build/examples

eg. this enrolls new fingerprint

examples/enroll

eg. to check if provided fingerprint is correct

examples/verify
