Comment # 19 on bug 1197723 from Wolfgang Rosenauer

There is also nothing new about it. That is how pcsc is "enabled" in openSUSE
since quite a while.

If something changed it might be some application which is accessing the pcscd
socket and then starts up the service for you.
The behavior seems to be the best approach to run pcscd for those with
corresponding cardreaders.

I'm also using a cyberjack reader via pcscd and at the same time an OpenPGP
enabled yubikey.

To make those work in parallel I had to configure ~/.gnupg/scdaemon.conf:

disable-ccid
pcsc-driver /usr/lib64/libpcsclite.so
reader-port "Yubico YubiKey OTP+FIDO+CCID 00 00"
