[138a:0090] Validity Sensors fingerprint reader not recognized

[Nikolay Makhotkin]

I have Lenovo Thnikpad X1 Carbon 4th Gen and it has 1382:0090 Validity sensor device.

I use Ubuntu 16.04.

Fprint won't recognize the device. Running fprint_demo, I receive a Status: No devices found message.

$ lsusb -s 001:006 -v

[Andreas Pflug (pgadmin-j)]

Same for me. Apparently, all newer Thinkpads are affected.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[albflo (albflo)]

Yes I can confirm this also for the Thinkpad Yoga 260!

[Artem Silenkov (asilenkov)]

Sadly protocol is crypted for X1 4Gen so no reverse engineering is possible.
More information is here: https://bugs.freedesktop.org/show_bug.cgi?id=94536

Having the same issue in my T470.

Someone managed to get it working. But only "if the device has been initialized with a Windows VirtualBox (sharing USB) guest or with a Windows installation in bare metal"

[Marco Trevisan (Treviño) (3v1n0)]

The device can also be initialized now using these tools:

Drivers requests are upstream bugs and as such should be redirected to the official wiki

As per this, I'm closing all the requests, I please you to update that wiki page if needed.
