It might give some clues - you'll have to try it.  The thing to look at
is CB_SOCKET_STATE, bits 1 and 2.  These are the two card detect bits,
and '1' means not detected, '0' means detected.  They both have to be
zero when the card is inserted.

You didn't look in the comments at the top of the file.  I guess that
also means I could've put a license on the file which required you to
do a John Cleese silly walk and email me the evidence immediately
before compiling it. 8)

This tells me that both sockets are reporting that they are empty.
(Socket status == CB_SOCKET_STATE)  Since we don't know any better,
we believe them.
