Unfortunately, GPG isn't taking input from the pinpad regardless of what
operations I am performing--signing, decrypting, change card
information.  This behavior is true of both the PIN and the Admin PIN.

Everything else that I have done so far with my OpenPGP v2 card works.
So I have no issues there.  Things such as generating a key, changing
card information, decrypting and signing e-mail work without any trouble.

I'll gladly answer any questions about my setup or tools or run
different stuff to debug this situation.  I just want to start using my
pinpad. :-)
