PC/SC Driver: SCardConnect blocked RRS feed

  • Question

  • We have wrote a PS/SC WDM driver for a USB Token. After connecting some (maybe 2, 3, or 4) clients to this driver via SCardConnect in SCARD_SHARE_SHARED mode, any client that wants to connect, will blocked at SCardConnect. Whenever one of previously connected clients leaves, an IOCTL_SMARTCARD_POWER (minnor: SCARD_WARM_RESETwill received by the driver and blocked clients will be unblocked and will be able to connect. After connecting some new clients (1, 2, or more) the process repeated again. The card works in T1 protocol.

    Is there any settings in PC/SC drivers, smart card readers or elsewhere that cause to this behavior? Do you have any idea about this problem?

    Note: This is not about smart card mini-drivers nor any other CSPs. The client is a PKCS#11 library.
