Re: SIM Trace Appears to Stop Processing APDUs

Harald, Thank you for your response.  I will try and summarize what we are seeing based on your questions below. The word 'freeze' is probably not accurate as the the simtrace application is still running/executing without receiving a termination signal, etc.  What we are experiencing is that the output, both with Wireshark and stdout, stops displaying any APDU traffic. For instance, when I boot up the phone for this first time, the simtrace application will appear to work correctly, but at some point during the reset it will stop displaying APDU traffic.  For instance on this run it stops after a response from the SIM: APDU: (183):  03 00 00 fa b0 00 00 00 2f 06 06 90 00 a0 a4 00 00 02 a4 6f 3a 9f 13 a0 c0 00 00 13 c0 00 00 0d 48 6f 3a 04 00 11 00 22 01 06 01 22 00 6f 06 03 90 00 a0 a4 00 00 02 a4 7f 20 9f 23 a0 c0 00 00 23 c0 00 00 00 00 7f 20 02 00 00 00 00 00 16 33 02 37 04 00 83 8a 83 8a 00 03 00 00 fa b0 00 00 00 00 2f 06 06 90 00 a0 a4 00 00 02 a4 6f 7e 9f 13 a0 c0 00 00 13 c0 00 00 00 0b 6f 7e 04 00 11 00 44 01 06 00 00 00 6f 06 06 90 00 a0 a4 00 00 02 a4 6f 07 9f 13 a0 c0 00 00 13 c0 00 00 00 09 6f 07 04 00 14 00 44 01 06 00 00 00 6f 06 03 90 00 a0 a4 00 00 02 a4 APDU: (7):  6f 07 9f 13 a0 c0 00 APDU: (7):  00 13 c0 00 00 00 09 APDU: (7):  6f 07 04 00 14 00 44 APDU: (7):  01 06 00 00 00 6f 06 APDU: (7):  03 90 00 a0 a4 00 00 APDU: (7):  02 a4 6f 07 9f 13 a0 APDU: (199):  c0 00 00 13 c0 00 00 09 6f 07 04 00 14 00 44 01 06 00 00 00 6f 06 03 90 00 a0 b0 00 00 09 b0 08 09 10 10 10 32 54 76 98 90 00 a0 b0 00 00 09 b0 08 09 10 10 10 32 54 76 98 90 00 a0 a4 00 00 02 a4 6f 78 9f 13 a0 c0 00 00 13 c0 00 00 00 02 6f 78 04 00 14 00 44 01 06 00 00 00 6f 06 05 90 00 a0 b0 00 00 02 b0 00 01 90 00 a0 a4 00 00 02 a4 6f 31 9f 13 a0 c0 00 00 13 c0 00 00 00 01 6f 31 04 00 14 00 44 01 06 00 00 00 6f 06 05 90 00 a0 b0 00 00 01 b0 00 90 00 a0 a4 00 00 02 a4 6f 30 9f 13 a0 c0 00 00 13 c0 00 00 96 96 6f 30 04 00 11 00 44 01 06 00 00 00 6f 06 04 90 00 a0 b0 00 00 96 b0 ff ff ff ff After this point it will no longer display (Wireshark or stdout) any APDU traffic.  The board itself shows no indication that there are any issues and the process 'simtrace' is still running.  If I restart the phone the only APDU I see is the ATR APDU. If I now stop the simtrace application and restart the application I will get the same result on boot up of the phone.  If I restart the application after the phone has been completely booted then I will see the status messages between the phone and the SIM for some period of time before that traffic also stops displaying to the screen. After a while I will see this error from the simtrace application: "Error submitting BULK IN urb: No error". An alternative phone will stop displaying APDUs, but at a different location from the first (this doesn't seem to be consistent): APDU: (7):  32 05 83 02 6f 42 a5 APDU: (7):  03 80 01 71 8a 01 05 APDU: (7):  8b 03 6f 06 07 80 02 APDU: (7):  00 fa 88 00 90 00 00 APDU: (7):  b2 01 04 32 b2 ff ff Please let me know if I can clarify/focus these issues.
