Did you try the cac bundle without any mods?

Deeper and deeper in the rabbit-hole I go...
So I recompiled everything with symbols so I can step through the whole
schlemiel, and I follow the ball all the way through slot_TokenChanged
to msc_IsTokenMoved to MSCIsTokenMoved to SCardStatus.
(Assuming I'm reading this right) SCardStatus builds up a struct, writes
it to pcscd, and then reads back the result into scStatusStruct. It
then tests the return value in scStatusStruct against SCARD_S_SUCCESS
and SCARD_E_INSUFFICIENT_BUFFER.
Unfortunately, the return value I have is -2146434968, which certainly
isn't either of these, so I'm dutifully dumped down through the stack
and a 1 gets returned from MSCIsTokenMoved--which is why
slot_TokenChanged thinks that the token has changed.
So the main bug is somewhere in the running server, or in the
commonAccessCard.bundle I cribbed from Darwin and modified per the Naval
Research Laboratory instructions. I'm thinking the latter. I've been
rapidly dusting off my ancient gdb skills, such as they are, but they
don't include debugging a running process. New things to learn...
However, if anyone has any input re: commonAccessCard.c, I'd love to
hear it.
