I am trying to make work my finger print sensor thinkpad x390 yoga. I installed printfd package using yay. When I try to run fprintd-enroll, I get this error:

Using device /net/reactivated/Fprint/Device/0
failed to claim device: GDBus.Error:net.reactivated.Fprint.Error.Internal: Open failed with error: The driver encountered a protocol error with the device.

When I try to run it for second time I get this:

Using device /net/reactivated/Fprint/Device/0
failed to claim device: GDBus.Error:net.reactivated.Fprint.Error.Internal: Open failed with error: Device 06cb:00bd is already open

I tried installing thinkfinger package but stillno luck. How can I resolve this problem ?

This is my lsusb output:

The solution was to update firmware of fingerprint device. I achieved by:

  1. Installing fwupd
sudo pacman -S fwupd
  1. Check if system can see device:
fwupdmgr get-devices
  1. Refresh firmware database:
fwupdmgr refresh --force
  1. Updating my firmware:
fwupdmgr update

You have to reboot immediatlly to apply update and prevent your device from weird behavior.


After all these steps fprintd-enroll will run without problems
