This is my first post to this list so a little introduction,

I work in security engineering for a large company that uses smart cards for authentication and encryption.

I am having trouble trying to use smart cards from an OSX client over Citrix. The same cards work from a Windows client. Hence the interest in being able to trace all APDUs in a non-OS specific format.

When I use simtrace with e.g. Gemalto Cyberflex cards, the APDU are shown as I would expect. 

However, when the card type is a Gemalto  Cryptoflex .NET alI see is the ATR APDU.

The Cryptoflex .NET cards are newer and supports a higher baud rate. Could this explain why the APDUs are not shown? There's a somewhat vague statement in the simatrace documentation to this effect.
