Description

After locking the session with hyprlock, fingerprint works as expected for a short while.
BUT if left for ~ 5 - 10 mins.
fingerprint stops working (the scanner stops scanning).
if i force fingerprint auth thought edits in /etc/pam.d/login
i get an error (Fingerprint device disconnected)

How to reproduce

Lock the session.
wait for 10 mins
try to unlock using your fingerprint

if i call CFingerprint::claimDevice() after i get a MATCH_DISCONNECTED, will it reconnect the device and fix this?

I also experience this - hardware is a Lenovo ThinkPad T14s Gen 3 AMD and I'm on NixOS unstable.
