running gpg --card-edit
CHECKPIN works
But PASSWD fails with "General Error" after the "enter PIN and new PIN" dialog
pops up, and pressing one key. Full log follows for both commands.

Retrying the passwd command several times inside "gpg --card-edit" consistently
fails no matter what I do before.
However, using "gpg --change-pin" only fails at most once in a row: the first
time it fails with general after the first key press, then retrying to change
the password succeeds, and subsequent changes succeed immediately and consistently.
But, if I cancel a pin entry, then I have a single failure, then it works (with
--change-pin).
Maybe some kind of buffer isn't flushed somewhere, and the first tries clears
it, but passwd in --card-edit doesn't...

The error value is 0x79, which means ERROR_SEM_TIMEOUT on Windows.
It seems for me that there was another application which tried to access the
smartcard and the reader, which interfered.
Did you use solely GnuPG?

Or, SCardControl default timeout is too short. GnuPG doesn't specify the
timeout, but uses 0x00 for bTimeOut, which means using default.
I don't know how we can change default timeout on Windows.
