This looks like a log from `examples/img_capture` which doesn't do anything except writing images to finger.pgm and finger_standardized.pgm (in case of elan they are the identical). The log is fine...

Thanks for the report! Unfortuantely, threre is still no way to configure the driver except by reading the device id. If you're comfortable with building from source, could you please...

Looks like you haven't installed libfprint after building it: `sudo ninja install`. If you did that then maybe the shared lib cache hasn't been updated. The safest thing to do...

If the scanner is recognized but enrolling and/or recognizing doesn't work well, then likely nothing can be done https://github.com/iafilatov/libfprint#common-problems

None that I know of that's available and fits libfprint's license. You can follow the development in the main repo at https://gitlab.freedesktop.org/libfprint/libfprint. It's quite lively and this problem is known....

Again, none that I'm aware of.

Try https://github.com/iafilatov/libfprint#unrecognized-devices Also, it's better to use the official repo https://gitlab.freedesktop.org/libfprint/libfprint

Thanks. Could you please rebase on [`elan`](https://github.com/iafilatov/libfprint/tree/elan) branch?

This code is rather old. You should try https://gitlab.freedesktop.org/libfprint/libfprint. But I can't say if it will work because your reader is returning an unexpected value for a certain command.
