Are you sure you're not mixing up the OSS CCID driver (which, yes, is meant for CCID compliant USB devices and should not deal with non-CCID drivers) and the pcsc-lite PC/SC interface/package in general?

If there existed a "standard" userspace<->kernel API which different SoC/embedded platform vendors could implement it would be as useful to the SoC scene as CCID is to the USB scene. Then a single and universal driver (ifdhandler) for pcsc-lite could be created just as the CCID driver is universal (so-so) for CCID devices. Eventually a stable kernel interface does good, the same way as creating a pcsc-lite compatible ifdhandler (even if it is more work in the beginning) does good to the application developers, as it provides the only universal and cross-platform access layer (PC/SC). Then again, I don't know how big would be the overlap between embedded and desktop PC/SC applications. -- Martin Paljak http://martin.paljak.pri.ee +3725156495 _______________________________________________ opensc-devel mailing list opensc-devel@lists.opensc-project.org http://www.opensc-project.org/mailman/listinfo/opensc-devel
