I've been able to use both the OTP and smart card parts of the NEO-n, but using them together hasn't worked well.
Removing and re-inserting the yubikey (which is what the OTP does) makes the card feature stop working with gpg. Windows Device Manager reports the reader and card are present, but gpg --card-status says this:
Code:
gpg: selecting openpgp failed: Card error
gpg: OpenPGP card not available: Card error
The only fix I have found is to restart Window's smart card service and also restart gpg-agent + scdaemon. Is there anyone with the same problem? Is there a way to debug why gpg is not working?
