Works after the following commands:

• install snap: https://snapcraft.io/docs/installing-snap-on-linux-mint
• update driver firmware: https://askubuntu.com/a/1316326
• configure fingerprint: https://forums.linuxmint.com/viewtopic.php?p=1845878&sid=a82d68ddad37a0835120a8f85b276256#p1845878

Works fine now!

Works fine on Linux Mint 20.1, but need to update sensor firmware first. Use snappy version of fwupd (>=1.5) to find the update available. You should also enable lvfs-testing. Commands:

apt purge fwupd
snap install fwupd --classic
fwupdmgr enable-remote lvfs-testing
fwupdmgr refresh --force
fwupdmgr update
fwupdmgr disable-remote lvfs-testing

Works with fprintd. Make sure you have updated the firmware with fwupd.

Works with fprintd.

Works fine on Ubuntu 20.04, but need to update sensor firmware first. Use snappy version of fwupd (>=1.5) to find the update available. You should also enable lvfs-testing. Commands:

apt purge fwupd
snap install fwupd --classic
fwupdmgr enable-remote lvfs-testing
fwupdmgr refresh --force
fwupdmgr update

Needs experimental firmware enabled in fwupd.

Firmware update needed. Once done, fprintd is able to detect the device and works.

fwupdmgr enable-remote lvfs-testing &&
fwupdmgr refresh --force &&
fwupdmgr update && 
fwupdmgr disable-remote lvfs-testing

Actually works out of box.

Need to enable lvfs-testing and update firmware using fwupd, and install fprintd and libfprint.

Works after update FW, it's need to install fwupd (version>1.5, via snap) and after run:

fwupdmgr enable-remote lvfs-testing &&
fwupdmgr refresh --force &&
fwupdmgr update && 
fwupdmgr disable-remote lvfs-testing
