Thank you for the dump. There are fingerprints and timestamps
registered on the card. But, it failed decryption with "No Record".
Usually, it means there is no key on the card.
Well, it's inconsistent. After writing private key onto the card,
fingerprint and timestamp are registered.
What's the output of 'gpg --card-status'?
By invoking 'gpg --card-status', scdaemon tries to access public key
on card. If it fails, I think that there were some troubles when you
wrote decryption key onto card (but it proceeded without notifying the
error, thus, having fingerprint and timestamps for decryption key,
I think that it's worth a try to run scdaemon with disable-ccid flag.
Please include a line:
It disables internal CCID driver and use PC/SC. If it works, there
is some bug in internal CCID driver.
