Framework Laptop 12 - USB ID of the new fingerprint sensor

Framework Laptop 12
1

Nirav mentioned, that they are using a new fingerprint sensor for the Framework Laptop 12. Can I ask, what’s the USB ID for this new sensor?

2

Is that the ID obtained via lsusb? I don’t have one myself, but maybe a new owner can get that for you!

3

Yes, exactly, you’ll get that ID with lsusb command.

just out of curiosity, why do you want that now?

if it’s to open a support request with libfprint, Framework stated they worked with the dev to get that supported day one

unless you have a USB firewall and want to preemptively register it?

the FW12 page for linux says libfprint v 1.94.100 is the minimum version, so it’s safe to assume one of the new USB IDs added in that release is the one used by the controller in the new fingerprint button

I can supply the ID of the fingerprint sensor on the Pro 13 - would that be the same one? This is a Goodix MOC sensor.

Nirav said in the deep dive video that (at 13:54)

We brought a new sensor here, from focaltech, and the teams been working very closely with the maintainer / the developer maintainer of libfprint...

Given this info, and the release notes, it’s likely the sensor listed in the release notes as:

focaltech_moc: New PID 0xA97

checking the source for libfprint, the VID for focaltech is 0x2808
