I am configuring an old HP Pavilion dv6-2120ew. It has a built in fingerprint sensor which is really important for my use case, but the new Ubuntu 20.04 LTS has problem with it (I don't know if there were problems with it before on previously installed Windows 7 Home).
When I try to set a new fingerprint, this is what shows up - "Problem Reading Device".
As in this question - How to use Fingerprint reader in Ubuntu 19.10 I checked
lsusb command and it gave the following output for the fingerprint device.
Bus 002 Device 003: ID 138a:0005 Validity Sensors, Inc. VFS301 Fingerprint Reader
Then I checked that it indeed is on the supported list - https://fprint.freedesktop.org/supported-devices.html
Since the default driver seems to be the correct one, I don't know what to do from now. Googling for this error doesn't give any results, except for the gitlab page with the code that issues this error.
The code isn't very informative though:
#: panels/user-accounts/cc-fingerprint-dialog.c:1100 msgctxt "Fingerprint enroll state" msgid "Problem Reading Device" msgstr "Arazoa gailua irakurtzean"
Any help would be greatly appreciated, as I am a Linux newbie.
