IIRC the on-device PIN entry is only used for signing operations, not
admin stuff -- so try proceeding anyway and then try signing.  This kind
of harms the point of having a on-device PIN entry, but it is still
possible to setup the card on a secure machine and then use it in other
environments.  I'm using a SPR-532 too with GnuPG on Mac for SSH
authentication, and I enter the PIN on the SPR-532 just fine.
