This is probably in scdaemon.  Thus you should add

--8<---------------cut here---------------start------------->8---
log-file SOMEFILE
verbose 
debug ipc,cardio
--8<---------------cut here---------------end--------------->8---

into scdaemon.conf, "gpgconf --kill scdaemon", and watch out for the
error message in the log file.  This likely an error code 0x6a88 from
the card, we need to see the commands prior to that.  Take care that you
redact the PIN in the log file.

That is not related.
