Hi,

I'm testing a new YubiKey 4.
the yubikey-personalization-gui for Linux v3.1.25 shows me at the upper right "Unknown firmware"

below the flasing images: Firmware Version 4.3.4.


What's going wrong?


Thanks

Frank

Make sure your version of yubikey-personalization is up to date (https://developers.yubico.com/yubikey-p ... ility.html).

Depending on the Linux build you will likely also need to update pcsc and add the udev rule for U2F devices (https://www.yubico.com/support/knowledg ... m-use-u2f/).

Hey,

I have the same question, therefore I don't want to start a new thread.

Bought a Yubikey Neo. Got "unknown firmware" warning, too.

Tested with recent windows binaries (App Version 3.1.24, Lib Version 1.17.3) and with the latest version from github with Linux (App Version 3.1.25, Lib 1.18.0) - both showed "unknown firmware".

My key a yubikey neo with firmware version 3.5.

Any advices?
Thanks!

Install 3.1.25, it'll fix the issue - https://developers.yubico.com/yubikey-p ... /Releases/

This page will be updated soon as well - https://www.yubico.com/support/knowledg ... ion-tools/

If you read my post, I already installed and tested it with app version 3.1.25.

I just tried with version 3.1.26 from the master branch and the issue still exists.

Linux - the library needs to be updated (yubikey-personalization)

https://developers.yubico.com/yubikey-p ... ility.html

1.18.1 is required for 3.5.X NEOs and 4.4.X YubiKey 4s.
