Hello,

I used the following options:

debug-level guru
debug-all
log-file /Temp/scd.log
enable-pinpad-varlen

Truncated output file showing two attempts to change the language from de to en
Notice no change in counters.

I also tried under FreeBSD and failed there as well which used the additional
debug-ccid-driver option

Of note, under FreeBSD, the orange light stays lit after entering the admin pin
(eventhough gpg2 rejects). Underwindows, it does not.

I include text here the FreeBSD reject just for comparison:
