The "3 0 3" are just fine. The 0 is for backward compatibility with 1.x

I assume that your gpg-agent and scdaemon are also from 2.0.19. That
should indeed work. To debug this you should enable debugging for
scdaemon by putting the lines
This will show what gpg-agent sends to scdameon. If it does not sent
anything, you can do the same for gpg-agent.conf. Still nothing? Add a
to scdaemon.conf and you will see all the data passing to and from the
card. This also shows the PIN and other information from the card; thus
you better edit the file before posting.
