I have a laptop with a fingerprint reader that is currently doesn't seem to be supported by linux (integrated in lenovo yoga 920).

But I am quite curious if it is at all possible for me to listen to events from it so that I might be able to do something with it. Totally not expecting to be able to do a full fingerprint read, but would be nice to try.

So question is, is it possible to get a raw read from hardware on the computer and how would I go about listing all devices/sensors installed?

  • Have you tried lshw (List HardWare)?

  • For live monitoring of plugging in devices, I find udevadm monitor -k to be rather helpful.... for monitoring the device action, usbhid-dump -e can be quite helpful. Fingerprint readers generally have rather poor support in most GNU/Linux distros... It's quite possible that the reader will require you to write your own kernel driver. Dec 30, 2018 at 21:28
