I apologize for the delay. I was waiting for the package to receive official support in Debian. Today, it was finally added to the official repository, but unfortunately, I wasn’t successful. Following your advice, I tried it on Ubuntu 22 with a Live USB, but again, I had no luck. I encountered the following error:
ubuntu@ubuntu:~$ fprintd-enroll
Using device /net/reactivated/Fprint/Device/0
failed to claim device: GDBus, Error:net.reactivated.Fprint.Error.Internal: Open failed with error: Please update firmware using fwupd
Then I tried your proposed tutorial from Debian but in the third step it simply ended in the middle without giving an error or anything and of course the sensor was still not working.
I also tried this other tutorial from Debian:
The tutorial developed properly but when doing:
fwupdmgr get-devices 1e8c8470-a49c-571a-82fd-19c9fa32b8c3
The result was the same as at the beginning and the fingerprint reader still did not work.
Already desperate, I tried to install Ubuntu on a USB and boot from there, from Ubuntu the fingerprint reader worked. Without saving any fingerprint, I started it in Debian and it worked. I don’t think this will be useful to anyone. But well. That has been my experience.
