At that debug level it is okay.  However with a higher debug level
(debug cardio) the log would show your PIN if you have used
disable-pinpad.  With a pinpad it won't show it, of course.

We fixed a reader bug in 2.2.26 which also changed how the SPR532 is
accessed.  See https://dev.gnupg.org/T5167 - Thus you better update to
the latest version first.

If you want to debug things, put

debug cardio
debug-ccid-driver

into scdameon.conf, kill and retry.  You may send the log to me by PM; I
would then only share it with my colleague Gniibe.


Salam-Shalom,
