Well, I've used the SCardControl functionality in my driver to send/receive commands from different types of USB devices (enhanced smartcard reader w/LCD, composite device, etc.) and it has worked very well for me.
In certain cases, I've had to use the SCardControl function as simply a transfer agent and marshalled/demarshalled my messages in the driver, but that wasn't much of a chore. If what you care about is this type of functionality, then you need to flesh out the IFDHControl function in your driver to handle the extended features of your device (ie. Read/write to LCD, etc.) Mike On 2/7/02 3:27 PM, "Joe Phillips" <[EMAIL PROTECTED]> wrote: > I have a smartcard reader device which includes extra features like LCD > display, keypad, motorized card feeder, and magstripe reader. > > Can I access these features through PCSClite?
