I just released version 1.5.2 of libccid the Free Software CCID class smart card reader driver.
1.5.2 - 31 January 2023, Ludovic Rousseau
--disable-usbdropdir
The AlcorMicro AU9560 smart card reader has problems with high speed smart cards.
The same problem is already reported in different places:
The reader is always the same but used with different cards.
The card must have a
TA1
> 0x95. To know the TA1 of your smart card you need to get and
parse the card's ATR, for example using pcsc_scan program from
pcsc-tools.
The reader declares it can support card/reader communication speed up to
688 172 bps.
See
dwMaxDataRate
field in
AlcorMicro_AU9560.txt.
It is fast but I have
4.5 % of readers in my list
that declare to be faster (not including contactless readers).
But speeds above ~200 000 bps are problematic with the AlcorMicro AU9560. It works fine, until an APDU exchange fails with a "Hardware error" (for example) message from the reader:
00000009 APDU: 00 A4 00 00 02 3F 00 00 00000007 ifdhandler.c:1333:IFDHTransmitToICC() usb:058f/9540:libudev:0:/dev/bus/usb/001/002 (lun: 0) 00000006 commands.c:1670:CmdXfrBlockAPDU_extended() T=0 (extended): 8 bytes 00000017 -> 000000 6F 08 00 00 00 00 0E 00 00 00 00 A4 00 00 02 3F 00 00 02734396 <- 000000 80 00 00 00 00 00 0E 41 FB 00 00000025 commands.c:1563:CCID_Receive Hardware error 00000009 APDU: 00 A4 00 00 02 3F 00 00
The AlcorMicro AU9560 is not a stand alone USB reader. It must be integrated
in a laptop. For example it is present in these laptop models:
I guess the same AlcorMicro AU9560 reader is present in a lot of other Lenovo or HP laptops and also laptops from other brands.
I worked on a patch to remove the highest speeds so that the CCID driver will negotiate a lower speed that is still supported by the reader.
My patch works fine with one card I have (NXP JCOP 4). But it generates problems with another card (Acos-ID).
The error occurs when the driver set the communication speed. The Set Parameters commands fails and the driver gets a "Card absent or mute" error.

I suspect the problem to be specific to this card. But I am not sure. That is why I need your help to test with as much possible combinations as possible.
If your have:
then you can help me.
The AlcorMicro AU9560 and the AlcorMicro AU9540 both use the same USB
idProduct value of 0x9540 even if the two readers are a bit different. So even
if you have a AU9560 the PC/SC name will be "Alcor Micro AU9540 xx yy". If you
do not know what reader you have just suppose you have a AU9560.
You can check the 2 conditions above (AlcorMicro and TA1 value) using the

Please do:
Your help will greatly improve support of this reader commonly found in laptops.
Thank you.
The patch is now included in the CCID driver and will be present in the CCID release 1.5.2 (to be released later).
The CCID driver version 1.5.2 is now available.
Support of the AlcorMicro AU9560 should be better now.
I just released version 1.5.1 of libccid the Free Software CCID class smart card reader driver.

In 2015 (7 years ago) I ported my CCID driver to UEFI (Unified Extensible Firmware Interface). For example read "UEFI Smart Card Reader Protocol implementation" and "PCSC sample in C for UEFI".
I now updated the driver to use:
The driver is no more a patch for edk2 but an independent UEFI driver in its own repository UEFI-SmartCardReader. It should now be easier to build.
I also updated my samples applications in UEFI-SmartCardReader-Samples.
This driver will not be used by a lot of people. The driver is for applications that are run in the UEFI (i.e. before the main operating system is started) and with a need to access smart cards.
If you use it and want to have new features, or just want to discuss, you can contact me. I am curious to know what people can do with it.
Just a quick article to talk about something funny.
Google Search Console Team sent me an email with the top most Google searches used to arrive on my website https://ccid.apdu.fr/.
For the month of June 2022 the second top search is: "ccid driver windows 10".
Google "think" someone will find a Windows 10 driver on https://ccid.apdu.fr/?
The Windows CCID is so hard to find or to install or is so buggy that users are searching for an alternative?
On the last 12 months the result is less worrisome. The "ccid driver windows 10" search is only 7th in the list:
Please propose your own explanation of this result.
Maybe I should add "Windows 10" in the web site description metadata to confuse Google search a bit more? :-)
Last year in "Accessing a lot of smart cards?" I wrote about accessing many smart cards in parallel.
One of my test platform was the sysmoOCTSIM, an 8-slots reader I presented in "sysmoOCTSIM: 8 slots reader". One advantage of this reader is that the 8 slots can be used at the same time. But my CCID driver did not support simultaneous access of different slots of the same reader.
Extract from the previous article (March 2021):
sysmoOCTSIM
My CCID driver for Unix do support multi-slot readers. But only one slot can be used at the same time. It is a limitation of the driver.
Supporting accesses to 2 or more slots in parallel would imply a change from synchronous USB communication to asynchronous USB communication. That is a possible change but not an easy one.
Results
number of slots sequential exe parallel exe 1 5.126s 5.126s 2 10.273s 10.030s 3 15.321s 14.944s
You may note that in the case of parallel execution we have a linear growth. As I explained before only one slot can be used at the same time. So pcsc-lite (the PC/SC resource manager) has to serialize the accesses to the different slots from the different executions.
The parallel execution is a bit more efficient than the sequential execution because part of the execution can be executed in parallel. But not so much.
My CCID driver now (since version 1.5.0) has support of simultaneous access to the slots of a reader.
But not all multi-slots readers can support simultaneous access. The reader
must declare that all the slots can be used the same time. The USB descriptor
field bMaxCCIDBusySlots must have a value greater than 1. Ideally
this value should correspond to the number of slots. My CCID driver enables
simultaneous access only if bMaxCCIDBusySlots correspond to the
number of slots i.e. bMaxSlotIndex +1.
Not so many readers will benefit from this improvement. They are:
So what are the performances now?
With the sysmoOCTSIM 8-slots reader I now get:
| # | User | Sys | Clock |
CPU |
|---|---|---|---|---|
| 0 | 0,07 | 0,02 | 24,65 | 0 % |
| 1 | 0,19 | 0,04 | 24,72 | 0 % |

| 6 | 0,50 | 0,11 | 24,64 | 2 % |
| 7 | 0,56 | 0,13 | 24,72 | 2 % |
I used the GNU time command to measure the User, System and clock times.
As expected the user (and system) time grows with the number of cards (slots) used.
Also as expected the clock time is rather constant to 24.6 seconds in all
cases instead of growing linearly as it was in the case in "Accessing a lot of smart cards?".
We can clearly see the effect of the simultaneous accesses here.
I got (remote) access to a sysmoSIMBANK 96 with 96 slots. See "A reader for 96 smart cards? sysmoSIMBANK" for more details about the reader.

Here again the user and system times grow linearly.
And again the total time is rather constant. The total time is multiplied by
1.5 while the number of cards goes from 1 to 88.
The CPU load is also growing linearly. The system has a 4-core CPU so it is not surprising to get more than 100% of CPU usage.
My sample test is not optimized for speed or CPU load at all. I use make -j to start one
Python program make has to start 88 Python processes
in the case of 88 slots.
The goal was to use standard and simple
tools.
I stopped at 88 slots instead of the expected 96 because one of the 12 sysmoOCTSIM reader (part of the sysmoSIMBANK 96 reader) was not working correctly at the time.
A big thank to Sysmocom for helping my work on this code.
I am very happy to see pcsc-lite and my CCID driver able to handle 88 APDU exchanges at the same time.
I just released
version 1.5.0 of
libccid the Free Software CCID class smart
card reader driver.
Multi-thread programming seams easy but it is difficult to write correct
multi-threading code.
For example pcsc-lite and my CCID driver use threads and are not (yet) perfect. One problem in particular is the access to the same variable from different threads.
C11 standard defines the Atomic types to make multi-thread programming easier.
This source code exhibits the problem.
#include <pthread.h>
#include <stdio.h>
enum CONSTANTS {
NUM_THREADS = 1000,
NUM_ITERS = 1000
};
_Atomic int global_a = 0;
int global = 0;
static void* main_thread(void *arg)
{
(void)arg;
int i;
for (i = 0; i < NUM_ITERS; ++i)
{
global_a++;
global++;
}
return NULL;
}
int main(void)
{
int i;
pthread_t threads[NUM_THREADS];
for (i = 0; i < NUM_THREADS; ++i)
pthread_create(&threads[i], NULL, main_thread, NULL);
for (i = 0; i < NUM_THREADS; ++i)
pthread_join(threads[i], NULL);
printf("global_a %d %s\n", global_a,
global_a == NUM_THREADS * NUM_ITERS ? "OK" : "FAIL");
printf("global %d %s\n", global,
global == NUM_THREADS * NUM_ITERS ? "OK" : "FAIL");
return 0;
}
If I compile and run the sample code I get:
global_a 1000000 OK global 660409 FAILor, with another execution:
global_a 1000000 OK global 691552 FAIL
You can see that the variable global that is NOT declared with
_Atomic does not have the expected value. Some updates of the
variable value failed (were skipped).
Another option if you do not want or can't use _Atomic is to use
pthread_mutex_lock() and pthread_mutex_unlock() to protect the accesses to the variable. But the code is
then harder to read.
The problem was reported by andrei-datcu in the pull request No data races in EHStatusHandlerThread.
I then fixed different problems in these changes (non-exhautive list):
And simplified the code by removing a mutex in Remove mutex and use _Atomic instead.
When a USB reader was removed you got error logs from the CCID driver. Something like:
00000000 [140295925790464] ccid_usb.c:871:WriteUSB() write failed (1/22): -4 LIBUSB_ERROR_NO_DEVICE 00000506 [140295934183168] ccid_usb.c:871:WriteUSB() write failed (1/22): -4 LIBUSB_ERROR_NO_DEVICE
The first error is because IFDHICCPresence() sends the CCID
command PC_to_RDR_GetSlotStatus to know if a card is present.
The second error is because IFDHCloseChannel() sends the CCID
command PC_to_RDR_IccPowerOff to power off the card.
But since the USB device has been removed these 2 CCID commands fails and logs the error.
I had to modify both pcsc-lite (the middleware) and libccid (the smart card reader driver) so they both cooperate to fix the problem.
Now when pcscd detects that a reader has been removed it uses
IFDHSetCapabilities() with the new tag TAG_IFD_DEVICE_REMOVED to indicate to
the driver that the reader has been removed and that there is no point in trying to
send commands to a no more connected reader.
The problem has been initially reported by a Fedora user at "Bug 2011128 - pcscd spam syslog when the laptop is undocked and the reader is connected through the dock".
Then Jakub Jelen from RedHat forwarded the bug upstream (to me) at "Reader disconnects are noisy in journal/logs #110" so I am aware of the problem.
The problem was then fixed 5 days later in "Use TAG_IFD_DEVICE_REMOVED when the reader is removed" for pcsc-lite and "Avoid logging errors when a reader is removed" for libccid.
The important point here is that users must reports bugs to their distribution. And distributions must report the problems upstream. It works well (in general).
What does not work is if you know of a problem and the problem does not come to me. For example this bug "Memory leak in pcscd" has been reported to pfSense 3 months ago and no one from pfSense took the time to report the bug upstream (to me). They just discussed about how to remove/disable pcsc-lite from pfSense instead.
I don't have a pfSense account so I can't comment on their bug tracker. I can't create an account on the bug trackers of every project that use my software. That is not how it is supposed to work. Distributors should forward bugs to the upstream projects.
I don't know if the problem is because pfSense is a commercial product or if it is because it uses FreeBSD. (be careful, a troll may be hidden in the previous sentence).
Don't be shy, report bugs.
Don't be shy, forward bugs upstream.

In a previous article "Accessing a lot of smart cards?" I presented a reader with 8 slots.
The same company, sysmocom, was also working or a reader with 96 slots. The reader is now available.
The product web page contains technical details and documentation.
The sysmoSIMBANK familly has two members:
96 slots in 2U 19” rack mount form-factor
192 slots in 4U 19” rack mount form-factor
On the USB bus the reader looks like 12 sysmoOCTSIM CCID devices connected
by some USB hubs.

You can see that not all the cards are identical. Some are faster (TA1=96) than other (TA1=95 or TA1=94).
The PC/SC reader name is composed of the constant part "sysmocom sysmoOCTSIM [CCID]", then the USB serial number of the sysmoOCTSIM (like "(196a76f633353553202020341b3b15ff)"), followed by the reader number and slot number.
We have 12 readers so from number 00 to 0B (0x0B = 11). Each sysmoOCTSIM has 8
slots so the slot number is from 00 to 07.
The maximum would be 256 readers with 256 slots each so a total of 65536
cards.
See "What is in a PC/SC reader name?" for more details about PC/SC reader names.
The 12 internal sysmoOCTSIM readers are independant readers so can be accessed
simultaneously. Because of a limitation of my CCID driver with multi-slots
readers I discussed in "Accessing a lot of smart cards?" it is not possible to access 2 slots of the same reader at the same time.
The accesses to slots of a same reader are serialized even if the reader could
allow simultaneous accesses.
I used the same code as in "Accessing a lot of smart cards?" to test the performances. I used only the first slot of each of the 12 sysmoOCTSIM reader
$ time make -j 0.test > /dev/null real 0m1.203s user 0m0.249s sys 0m0.053sThe measures are:

We get the graph:
The system has a 4-core CPU so it is expected that the "real" time is/can be lower than the "user" time.
What is important is that the "real" time grows much slower than the number of readers. The time should even be constant in all cases since the 12 readers can work in parallel, but I guess we have a contention on the USB bus since all the accesses are using the same USB connection. So some serialization has to be done at the USB level.
You can note that to handle 12 cards is it only 2.01 times slower than to handle 1 card. We have a speedup of 6 here.
The reader also has 3 Gigabit Ethernet interfaces (RJ45) so the USB limitation may not be a problem. Note that my CCID driver does not know how to talk to this reader using a network protocol.
Both pcsc-lite and my CCID driver work fine with 96 slots/cards. That is good to know because that is not a setup I used to test and debug the software. I guess it is not a very common setup 😀.
I have no problem making "advertising" for sysmocom products because the company is on the Free Software side of the force. All the software they provide, including the sysmoSIMBANK reader firmware, is Free Software (GNU GPL v2+) and I am happy to give them some visibility.
Thanks to sysmocom for giving me access to the reader.
