Thanks @kubrick, looks good on my side as well.

Thanks @Piscolero! I have implemented your solution. Let me know if it works for you (it does for me).

Just a small hint.

To fix the warning /usr/lib/udev/rules.d/60-libfprint-2-tod1-goodix.rules:2 Unknown group 'plugdev', ignoring. the udev rule should use TAG+="uaccess" instead of GROUP="plugdev".

AFAIK, unless it’s in a Dell laptop “Developer Edition”, then no.

Would there have any plan for the support of 27c6:532d (XPS 13 2-in-1 (9310))?

I don't think it's got anything to do with crypto.

It's just that it's closed source and undocumented, so it would be a lot of effort to implement a full open source driver, and illegal to distribute a modified version of the binary.

Oh okay. Sorry, should have checked the id more carefully. I guess there must be some crypto embedded for that level of certainty that it will never be reverse engineered.

@zugnush your device is not supported by this driver

Also it has been added to https://gitlab.freedesktop.org/libfprint/wiki/-/wikis/Unsupported-Devices

"support is unlikely to ever happen"

I think I've covered all the bases but keep getting no device. Any advice?

@rolandd

thank you. Your suggestion partially worked. Downgrading to fprintd-1.90.6 did allow me to enroll finger prints, however, when starting the fprintd service is craps out with:
