Hello!
I propose a patch for src/libopensc/card-westcos.c if it's working.
src/libopensc/card-westcos.c:westcos_select_file:
309:case SC_PATH_TYPE_PATH:
apdu.p1 = 9;// Why is it needed? (9 ?)
336:if (file_out != NULL) {
apdu.resp = buf;
apdu.resplen = sizeof(buf);
apdu.le = 255;
} else {
apdu.resplen = 0;
apdu.le = 0;
apdu.cse = SC_APDU_CASE_3_SHORT;
}
Is this correct? (See
http://www.opensc-project.org/opensc/changeset/3700/trunk/src/libopensc
and
http://www.opensc-project.org/pipermail/opensc-devel/2009-June/012280.html)
Patch for trunk revision 3741 attached.
Thanks
