Issues with fingerprint reader
Hello, I'd like to enable finger print login for my laptop.
I've followed the wiki article for fprint and installed fprintd and libfprint-elanmoc2-newdrvs (I already had imagemagick installed). The output of
yay -Q | grep -i fprintis:
fprintd 1.94.2-2
libfprint-elanmoc2-newdrvs-git 1.94.0+11+g32b8a2d-1I installed the latter library because from lsusb I can see that I have an ELAN device with ID 0c00, which is not in the supported devices list, but is however mentioned in the wiki article in the installation section.
Now, when I try to enroll a fingerprint, I get different errors, seemingly at random.
I have GNOME and GDM installed, so I tried enrolling fingerprints from the GNOME settings panel. Sometimes, I reach the end of the enrollment process and get the "Problem Reading Device" error. Other times, for a brief moment, the operation succeeds and then errors out, allowing me to save the fingerprint by clicking on "Done" in the pop-up window.
I have dumped my system journal after a reboot and followed the same procedure to show the errors fprintd encounters:
