Enable logging for the scdaemon.  Put the following into
~/.gnupg/scdaemon.log

--8<---------------cut here---------------start------------->8---
log-file /foo/bar/scd.log
verbose
debug ipc,cardio
--8<---------------cut here---------------end--------------->8---

Restart and have a look at the log.  

> gpg: DBG: chan_3 <- D 2.4.9

This reched end-of-life so you better update to a current version.  See
repos.gnupg.org for Debian style packages.


Salam-Shalom,
