Fingerprint driver for GNU/Linux

I've found a driver which can possibly support these kinds of fingerprint readers: https://salsa.debian.org/rousseau/CCID

I compiled it (and its dependency PCSC), the install instruction is not super user friendly, but I was unable to configure it properly for fprintd and it did not recognize the reader.

Maybe someone else will have better luck with it. Please keep us informed of you succeed.

(Dell Latitude 5520)

Hi, thanks for the link!

I tried to build the drivers, but It seems that only the smart card is working:

I've just mailed to the driver's developer asking about it.

Hi @subaKG The developer replied and explained to me that CCID is a specification for smart cards only

Our beloved 0a5c:5843 device is supported, but the smart card feature only.

Seems like it might be fun to try to implement it hehe. Might have a play around soon and report back.

Looks like the CCID driver just doesn't have the scope to support the device.

The included parse program just states that the 0a5c:5843 device is not a CCID/ICCD device

Parsing USB bus/device: 0A5C:5843 (bus 1, device 4)

 NOT a CCID/ICCD device

It's probably better to just try to add support to libfprint. ¯\_(ツ)_/¯

Hello @szaffarano, thanks for the notif. Wondering when will dell or the reader's manufacturer implement a linux driver for this device...

Until then we have to stick to typing passwords...

With a fresh install of Ubuntu 20.04.3 on a Latitude 7420 the 0a5c:5843 Broadcom fingerprint reader is working! I had to go into Software & Updates -> Additional Drivers and move the radio button to "Using Broadcom fingerprint TOD driver from libfprint-2-tod1-broadcom (open source)". Then I was able to add fingerprints in Settings -> Users, open a terminal, run pam-auth-update, and enable Fingerprint authentication. I also just got it working on my Latitude 9410 with the same reader, running 21.04. They both have the libfprint-2-tod1 package installed. The trick is to enable the Canonical Partners repo for somerville and somerville-melissa (on 9410 and somerville-squirtle on 7420), then go back into Additional drivers and switch the radio button to use the newly found driver. I'm stoked and I hope this helps others!

You're very welcome! 

Hey! Thanks so much @jermaine151 !!!!!!

Huzah! I got it working on Arch! Wrote a pkgbuild to grab the libfprint-2-tod1-broadcom package from the Ubuntu repositories.  I then installed libfprint-tod-git from the AUR (you will have to configure the PKGBUILD to ignore the tests, three tests fail and I can't be bothered to find out why). There's a python script that comes with libfprint-2-tod1-broadcom which installs the firmware to the fingerprint reader and I do not know how I am supposed to package it. I have left it out but running the script is likely necessary. From now on you should be able to fprintd-enroll your fingerprints!

I'm going to put the libfprint-2-tod1-broadcom package on the AUR.

fprintd fails to pick up this driver on my Debian

Please see my comment on how I got it working on Dell Latitude 5400
https://github.com/dsd/fprintd/issues/3#issuecomment-962422370

I was able to get it working by updating the fprintd version. 

It's working for some time now, but the fingerprint device would disappear (disconnect from the USB bus) after I suspend the system a few times. 

I have that same problem and rebooting is the only way that I can get it working again. 

Same problem here! I didn't find a root cause but after a while (around once every three days) I have to reboot the laptop (or stop using the fprintd).  I get a lot of "Error: 0x1c" error messages, and if I try to restart the fprintd service: "Ignoring device due to initialization error: An unspecified error occurred!"
