I get the "Exception: Failed: 04af" error when the python3-validity.service starts. Maybe the binary blobs need an update? There is a newer driver at the Lenovo site:

Interestingly, I can't enroll my fingerprint on Ubuntu 20.04. I got this exception:

0401
Traceback (most recent call last):
File "/usr/lib/python-validity/dbus-service", line 161, in run
sensor.enroll(usr, index, update_cb)
File "/usr/lib/python3/dist-packages/validitysensor/sensor.py", line 828, in enroll

raise Exception('Failed: %04x' % s)
Exception: Failed: 0401

if you have solution for it, please let me know

Restarting it solved this problem:

sudo systemctl restart python3-validity

hey @osbre , can you confirm it's working for you /fingerprint setup/function properly? Somewhere else I read, it seems that this finger-printer reader isn't supported: https://github.com/uunicorn/python-validity/issues/71

I am using a thinkpad carbon x1 gen4, with also 138a:0090, I am on ubuntu 22.04, I am encountering the same problem as listed in this issue. Perhaps it works on elementary OS?

thanks
