WTH,
If its a smart card reader, one of the 'common' makes and you are running XP
then the Smart Card service will grab the reader for Logon. If this is the
case then you are probably not checking that you are opening the port
correctly.
If it is a smart card reader, then it would be best to use the smart card
API.
