Linux

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Has anyone here had success with USB fingerprint scanners? I also found this Microsoft keyboard with fingerprint reader but I don't know if it works with linux.

Here's the list of devices supported by fprint

For non -standalone readers, you'll have to look up the actual fingerprint reader embedded within it.

Edit: it looks like this is a Bluetooth keyboard. My guess is it's highly unlikely to work with Linux as a fingerprint reader.

It's a shame that that the list doesn't translate well into "what device can I go out and buy"? Every shitty manufacturer has to constantly churn design changes, and hide it all behind the exact same model number.

I use the DigitalPersona 4500 with libfprint. Unfortunately, there are multiple revisions of the device with the same model number and only some of them work properly under Linux (different encryption method I believe). As far as I know this is not actually documented anywhere. Googling just shows a bunch of unresolved bug reports of people having no idea why it doesn't work.

Would you mind sharing your lsusb output?

Bus 001 Device 059: ID 05ba:000a DigitalPersona, Inc. Fingerprint Reader

It shows up exactly the same for all the revisions though.

Almost every one of the fingerprint sensors in laptops are not supported by Linux due to proprietary protocols. Never managed to get stuff used by Dell or HP with Linux.

But the Grow R503 can be used over uart, what can be connected to usb with some minor additional parts.

Thankfully the Framework Laptop fingerprint reader works.

That's why I'm buying it because they've got actual Linux support (and because of being able to reconfigure it for the task at hand)

I recently got a Dell Latitude 14 2-in-1 with the AMD 8840U, Put on the latest Fedora Kinoite and the fingerprint reader works FYI.

same here but I have a Dell Inspiron 7415 2-in-1. Just installed fedora and it worked out of the box.

same with my old Lenovo P53 (for years) -I needed adding some packages though, but that was so long ago...

That sucks so much. I have such a cool vein scanner built in to unlock my laptop jedi style and I can't use it because Fujitsu decided to not add support for Linux 🙄

T480s here works on Ubuntu.

HP Zbook 15" G7 working out of the box but not great detection reliability (might be an unfortunate specimen). Lenovo Thinkpad T580 much better although not working out of the box on LMDE
