<html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body>Hi everyone, I would like some advice on how to support a new finger print reader device from synaptics that is currently not supported in fprint added to the list. Do let me know what information is required. This is what I have been able to dig up until now. 🕙 02:17:19 ➜ lsusb Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 04f2:b690 Chicony Electronics Co., Ltd HP HD Camera Bus 001 Device 002: ID 06cb:00c4 Synaptics, Inc.

AX200 Bluetooth Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub I believe the device is a synaptics device - haven't been able to dig in more but looks like there are very similar prod vendor id's that are already supported in the codebase. Do I need anything else other than libfprint - I run gnome 3.38.3 but still can't find the finger print options in my user management - I tried fingerprint-gui as well but no luck there. I attempted to build it in myself by adding the new prod id in the code base - not sure where to go from here - I figured since it is the same vendor they may have the same interface and commands - but I think I need some direction from here - not too familar with the meson build system and how to go from here.

I am willing to help with coding testing etc. Thanks, Frino </body> </html>
