Today I'm also setting up a bunch of V3.3 cards.

There is indeed a problem: OpenSC added support for the new cards just
in the current git HEAD version. See:

-> we compiled opensc from git on Fedora now are able to talk to the card.

You might be affected by this if gnupg talks to the card
via opensc instead of the builtin libusb based CCID driver.
(that's what NIIBE Yutaka suspected in his reply)
