FIDO2 Card w/ Card Reader Not 'registering' in Chrome / Firefox

Ask Fedora
1

I have F41 on a desktop, with Win11 dual boot. My Cryptnox FIDO2 card and card reader work great on Win11, BUT F41 only seems to have OS-level support (no browser support). I ran tests using: https://webauthn.io

I installed / ran these packages / services as such:

sudo dnf install -y --skip-broken --skip-unavailable pcsc-tools fido2-tools nss-tools pcsc-lite perl-pcsc pcsc-tools ccid opensc pam-u2f pamu2fcfg

sudo systemctl start pcscd

sudo systemctl enable pcscd

CLI hardware telemetry suggests F41 detects the card / reader FINE. Firefox even has it in it’s ‘security devices’ list as well.
