I assume you mean "stop polling for CARDS". the ccid spec supports using an interrupt pipe message to notify the host of card insert/remove events, but devices are not required to implement that part. Even for devices that do, I don't understand enough of how usb and libusb handle interrupt endpoints to know if the messages are buffered indefinitely, or only when there's an outstanding urb. In any case, there is no asynchronous notification of the insert/remove events, so openct would still have to poll the ifd to get the data. If you just don't want to provide the card insert status to clients, then ccid's feature is irrelevant _______________________________________________ opensc-devel mailing list opensc-devel@lists.opensc-project.org http://www.opensc-project.org/mailman/listinfo/opensc-devel
