There was not much discussion about this post.
pcsc-lite is a framework for smart card reader drivers or ifdhandlers, much like OpenCT. There are different classes of drivers, like USB, PCMCIA or SoC. I don't see why everything should be jammed into libccid which is a driver for a certain class of hardware. Different driver classes should have a different driver. >From source perspective, the "trouble" you're mentioning is the possible need >for code duplication for protocol handling, which seems like a pain but can be >arranged differently than by creating a hybrid driver. In addition to the behavior problems Alon has been talking about (sleeping, polling) and API questions (OpenCT != PC/SC) the way to reduce code duplication could maybe be to crate a mini-framework for proprietary (USB, SoC, Serial) protocols for pcsc-lite. > This is a post from Andreas Jellinghaus, published on Tue, 20 Apr 2010 > 20:50:56 +0200.

Do you want to say that libccid currently does not handle T=1? Upgrading to libusb 1.0 when appropriate is of course a good thing. -- 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
