OpenPGP card not accessible; ctapi-driver option in gpg.conf does the job for me (with cyberjack reader)

Well, I have no immediate plans to drop the support but I can't test the
ctAPI driver.  Thus you are on your own if you want to use it.

By disabling the SCdaemon, you use the code included in gpg 1.4.  That
is the same code as used in scdaemon.  The problem you encountered is
likely due to problems in Scdaemon 2.0.10 (or earlier).  2.0.11 fixes
them for me.
