YubiKey 5C NFC not detected

[Felix E. Klee]

I would like to set up a YubiKey 5C NFC for SSH, but it doesn’t get
detected by GnuPG:

    $ ykman config usb -l
    OTP
    FIDO U2F
    FIDO2
    OATH
    PIV
    OpenPGP
    YubiHSM Auth
    $ cat .gnupg/scdaemon.conf
    reader-port Yubico Yubi
    $ gpgconf --kill gpg-agent
    $ ps x | grep scdaemon
      33408 ?        SLl    0:00 scdaemon --multi-server
      49465 pts/2    S+     0:00 grep scdaemon
    $ /usr/lib/gnupg/scdaemon --version
    scdaemon (GnuPG) 2.2.32
    libgcrypt 1.9.4-unknown
    libksba 1.6.0

    $ gpg --verbose --card-status
    gpg: selecting card failed: No such device
    gpg: OpenPGP card not available: No such device

What can I do?
