    There is a smartcard chip embedded in a PnP device of completely irrelevant
    class. It is not exposed as independent hardware function.
    The chip can be accessed only thru the driver of this device.
    How I can make this chip visible to CryptoAPI from user mode?
    Can this be done with a user mode module that sends custom ioctls to the
    Or I need a root enumerated driver that emulates a Smartcard reader?
    Can such "virtual" smartcard readers pass HCT?

  2. So who uses the Smartcard chip? The "PnP device of a completely irrelevant
    class"? Does the chip present an ATR when requested?

    You can write a driver that will function as a Smartcard reader, but
    gettiing it thru WHQL is going to be a problem since the first thing that
    IFDtest asks you to do is insert a card. You would use the Universal program
    to get it through certification. I have the same problem since my harddisc
    thinks its a Smartcard ... LOTS and LOTS of Smartcards.
