Hi,
we have some cards that work fine on Windows with CCID readers,
and also fine with the non-CCID ACRS38U reader on Linux.
But on Linux with 4 CCID readers, some cards have some
communication problem. Every few 100-200 APDUs, there's a delay
of 60 sec between the command and the response APDU; after which
the communication just continues (until the same problem occurs
some time later). It happens with various commands (Read Binary,
Select File, Verify PIN, ..)
So from the same batch of cards (with the same chip and OS), some
have the above problem and some not.
Below are the end of the CCID and USB logs, where we send the
same Read Binary to the card, until we got the 1 minute delay.
It looks like the CCID log says that the ccid driver had to wait
for 1 minute before the response APDU came in; while the USB
log (2nd row = time in µsec) seems to suggest that the response
APDU was actually send back to the PC (??)
Here's the ATR is, it's a pretty fast card.
ATR: 3B 7D 95 00 00 80 31 80 65 B0 36 01 01 C8 83 01 90 00
TS = 0x3B --> Direct Convention
T0 = 0x7D --> Y(1): b0111, K: 13 (historical bytes)
TA(1) = 0x95 --> Fi=512, Di=16, 32 cycles/ETU (125000 bits/s at 4.00 MHz,
156250 bits/s for fMax=5 MHz)
TB(1) = 0x00 --> VPP is not electrically connected
TC(1) = 0x00 --> Extra guard time: 0
If someone has any idea of what might be happening here...?
Thx,
Stef
