None the wiser:

    $ cat ~/.gnupg/scdaemon.conf
    debug cardio
    log-file /tmp/scd.log
    $ gpgconf --kill gpg-agent
    $ gpg --card-status
    gpg: selecting card failed: No such device
    gpg: OpenPGP card not available: No such device
    $ cat /tmp/*.log

Good to know.  Will keep an eye on it.  Even if 2.2 doesn’t work with
that YubiKey, it does work just fine with the OpenPGP smart card in my
[SPR232 mod][1].  So I don’t want to loose access there.
