Hi Mikael,

The main problem with Leopard is bug in pcscd, which is
still not fixed 
in 10.5.2. The daemon appends 0x00 to the ATR, and probably
your card is 
not recognized anymore by OpenSC.

You can check the reported ATR with
/Library/OpenSC/bin/opensc-tool -a 
(do it a least twice because sometimes, at the first run the
ATR is 
correctly reported...).

Then create an entry in /Library/OpenSC/etc/opensc.conf with
something 
like this:
card_atr 3B:7D:11:00:00...... {
    driver = your_card_driver
    type = value
    }

Sometimes you need to define a type too. Check for your card
in 
http://www.opensc-project.org/opensc/bro
wser/trunk/src/libopensc/cards.h 
to get this value.

Cheers,

Jean-Pierre

The attached patch for src/libopensc/card.c should fix the
problem  
with the additional zeros appended to the ATR for all ATR
related  
lookups inside OpenSC.

In theory the patch checks on Apple platforms if the ATR
happens to be  
MAX_ATR_SIZE long and for a given ATR match the tail of the
ATR from  
PCSC contains only zeros, it assumes it is running with the
buggy PC/ 
SC implementation.

Give it a try/view and send your feedback/comments.
