I will use patch files in the future. Sorry for the trouble.

Just in the case you wondered why there is support for D-Trust Card 4.1/4.4 
and 6.1/6.4 in GnuPG, but not for 5.1/5.4: The 5.x-series is a dual interface 
card (contact based and NFC) and requires to establish a secure channel via 
PACE [1] on both interfaces. Are there plans to eventually support PACE in 
scdaemon? It's not a problem for me if not, but maybe this kind of cards will 
become more and more widespread in the future.
