[HOLD]Is there no fingerprint support for 06cb:0102 Synaptics, Inc.

I have a laptop Acer Aspire 7 (A715-76G) and it seems to have a fingerprint device with ID "06cb:0102". I can neither find it's support in fprintd nor anywhere else and official website only shows "Windows 11" for driver support

It's not even listed on unsupported devices

the 06cb corresponds to a synaptics device , but 0102 is not listed on https://usb-ids.gowdy.us/read/UD/06cb .

https://linux-hardware.org/?id=usb:06cb-0102 shows no reports of systems where it functions under linux .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Have you tried adding the device ID to libfprint? You could use the addition of 06cd:0104 as a template.

It seems the the device is a very new one. Neither the laptop have much driver updates.

libfprint-1.94.7-3.1-x86_64.pkg.tar.zst.

I have tried that, it ain't working. It just says "Ignoring device due to initialization error: unsupported firmware version"

Also, fwupd isn't even showing the device/firmware.

I would suggest contacting the libfprint project.

I will mark the topic as [HOLD] for now then.
