Hi,

I installed Manjaro KDE on my laptop Lenovo Ideapad 720. Tried to set fingerprints using fingerprint-gui, but no device is found.
lsusb:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 06cb:0081 Synaptics, Inc.
Bus 001 Device 004: ID 8087:0a2a Intel Corp.
Bus 001 Device 003: ID 174f:241a Syntek
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I’m not even sure if reader is listed here.

Thanks you in advance for every advice.
Jakub
