Hello, Marc, thank you for your time.

OK.  That's Yubikey.  I'm going to reproduce with Yubikey.  (My claim
in the previous mail (saying no problem) is not for Yubikey, but other
OpenPGPcard/token.)

Yubikey has applications other than GnuPG.  For authentication, there
are OTP and UDF.  I think that it is likely those features interfere
somehow.

Do you install some other packages for OTP/UDF/PIV?  Are there any
difference between your Fedora and Mac OS/X with regards to
OTP/UDF/PIV usage?

Actually, killing scdaemon is a bit difficult (we need to invoke kill
two times).  If it's 2.1.x, please do: gpgconf reload scdaemon

Also, let me try with my Yubikey.
