I can't say about OpenSC. But at the PC/SC level pcsc-lite is limited to 16 readers by default. You can change PCSCLITE_MAX_READERS_CONTEXTS in PCSC/src/pcsclite.h.in for another (greater) value and rebuild pcsc-lite. Or you can propose a patch to use a list instead of a fixed size array to definitely solve the problem :-) Regards, -- Dr. Ludovic Rousseau _______________________________________________ opensc-devel mailing list opensc-devel@lists.opensc-project.org http://www.opensc-project.org/mailman/listinfo/opensc-devel
