(at91lib) cciddriver.c: // 6.3.1 RDR_to_PC_NotifySlotChange #define ICC_NOT_PRESENT 0x00 #define ICC_PRESENT 0x01 #define ICC_CHANGE 0x02 #define ICC_INSERTED_EVENT ICC_PRESENT+ICC_CHANGE (libccid) ccid.h: /* See CCID specs ch. 4.2.1 */ #define CCID_ICC_PRESENT_ACTIVE 0x00 /* 00 0000 00 */ #define CCID_ICC_PRESENT_INACTIVE 0x01 /* 00 0000 01 */ #define CCID_ICC_ABSENT 0x02 /* 00 0000 10 */ #define CCID_ICC_STATUS_MASK 0x03 /* 00 0000 11 */ There is no 0x03 case in libccid, which is what causes the obscure communication error 612. SIMtrace firmware returns 0x03 on startup, regardless of SIM insertion state. I can probably fix this, though I wonder why the problem wasn't there before.. Cheers Tom
