Description of problem:

DNIe is the official Spanish ID card, which includes an electronic smart card
with a PKCS#11 certificate.

I'm trying to use it to sign some PDF documents, but gpg is unable to contact
the card.

Version-Release number of selected component (if applicable):

gnupg-1.4.20-1.fc23.x86_64
gnupg2-2.1.11-1.fc23.x86_64
opensc-0.15.0-4.fc23.x86_64
pcsc-tools-1.4.25-1.fc23.x86_64
pcsc-lite-ccid-1.4.20-1.fc23.x86_64
gnupg2-smime-2.1.11-1.fc23.x86_64

How reproducible:

Steps to Reproduce:

1. Insert DNIe in slot.
2. gpg2 --card-status

Actual results:

gpg: OpenPGP card not available: Not supported

Expected results:

Card available.
