Supported operating systems:
|
| 57 |
============================
|
| 58 |
|
| 59 |
- GNU/Linux (libusb 0.1.7)
|
| 60 |

|
| 61 |
to libusb)
|
| 62 |
|
| 63 |
|
| 64 |
Debug informations:
|
| 65 |
===================
|
| 66 |
|
| 67 |
The driver uses the debug function provided by pcscd. So if pcscd sends
|
| 68 |
its debug to stdout (pcscd --foreground) then the CCID will also send
|
| 69 |
its debug to stdout. If pcscd sends its debug to syslog (by default)
|
| 70 |
then the CCID will also send its debug to syslog.
|
| 71 |
|
| 72 |
You can change the debug level using the Info.plist configuraion file.
|
| 73 |
The Info.plist is installed, by default, in
|
| 74 |
/usr/local/pcsc/drivers/ifd-ccid.bundle/Contents/Info.plist
|
| 75 |
|
| 76 |
The debug level is set in the ifdLogLevel field. It is a binary OR
|
| 77 |
combinaison of 4 different levels.
|
| 78 |
- 1: critical: important error messages
|
| 79 |
- 2: info: informative messages like what reader was detected
|
| 80 |
- 4: periodic: periodic info when pcscd test if a card is present (every
|
| 81 |
1/10 of a second)
|
| 82 |
- 8: comm: a dump of all the bytes exchanged between the host and the
|
| 83 |
reader
|
| 84 |
|
| 85 |
By default the debug level is set to 3 (1 + 2) and correspond to the
|
| 86 |
critical and info levels.
|
| 87 |
|
| 88 |
You have to restart the driver so it read the configuration file again
|
| 89 |
and use the new debug level value. To restart the driver you just need
|
| 90 |
to unplug all your CCID readers so the the driver is unloaded and then
|
| 91 |
replug your readers. You can also restart pcscd.
|
| 92 |
|
| 93 |
|
| 94 |
Known problems:
|
| 95 |
===============
|
| 96 |
|
| 97 |
1. USB timeout
|
| 98 |
""""""""""""""
|
| 99 |
Some readers do timeout when a special USB frame is sent from the
|
| 100 |
reader. If the frame size if a multiple of wMaxPacketSize the
|
| 101 |
communication is stopped. You should contact the reader vendor to
|
| 102 |
upgrade the firmware of the reader or replace the reader.
|
| 103 |
|
| 104 |
2. Kernel 2.6
|
| 105 |
"""""""""""""
|
| 106 |
The reader works fine with Linux kernel 2.4 but does not with Linux
|
| 107 |
kernel 2.6. The ioctl() syscall returns EINVAL (Invalid argument)
|
| 108 |
|
| 109 |
3. MacOSX libusb
|
| 110 |
""""""""""""""""
|
| 111 |
There is a bug in libusb that crash the libusb library when you
|
| 112 |
unplug a reader and replug it in another USB socket. So if you
|
| 113 |
unplug a reader replug it in the same USB socket.

History:
|
| 137 |
========
|

|
| 139 |
0.9.0 - 1 July 2004, Ludovic Rousseau
|
| 140 |
- The T=1 TPDU automata from Carlos Prados' Towitoko driver is very
|
| 141 |
limited and do not support error management mechanisms.
|
| 142 |
I then used the T=1 TPDU automata from OpenCT (OpenSC project).
|
| 143 |
This automata is much more powerful but still lacks a lot of error
|
| 144 |
management code.
|
| 145 |
I then added all the needed code to reach the quality level
|
| 146 |
requested by the EMV standard.
|
| 147 |
- add support for new readers:
|
| 148 |
. Advanced Card Systems ACR 38
|
| 149 |
. Cherry XX33
|
| 150 |
. Dell keyboard SK-3106
|
| 151 |
. Dell smart card reader keyboard
|
| 152 |
. SCR 333
|
| 153 |
- add support of multi procotol cards (T=0 and T=1)
|
| 154 |
- the debug level is now dynamic and set in the Info.plist file (no
|
| 155 |
need to recompile the driver any more)
|
| 156 |
- add support for the libusb naming scheme: usb:%04x/%04x:libusb:%s
|
| 157 |
- INSTALL: add a "configuring the driver for the serial reader
|
| 158 |
(GemPC Twin)" part
|
| 159 |
- use `pkg-config libpcsclite --variable=usbdropdir` so you do not
|
| 160 |
have to use --enable-usbdropdir=DIR or --enable-ccidtwindir=DIR
|
| 161 |
even if pcscd does not use the default /usr/local/pcsc/drivers
|
| 162 |
- add support of IOCTL_SMARTCARD_VENDOR_IFD_EXCHANGE and
|
| 163 |
IOCTL_SMARTCARD_VENDOR_VERIFY_PIN in IFDHControl()
|
| 164 |
- read ifdDriverOptions from Info.plist to limit the use of
|
| 165 |
IOCTL_SMARTCARD_VENDOR_IFD_EXCHANGE (idea from Peter Williams)
|
| 166 |
- provide an example of use of SCardControl()
|
| 167 |
IOCTL_SMARTCARD_VENDOR_IFD_EXCHANGE and
|
| 168 |
IOCTL_SMARTCARD_VENDOR_VERIFY_PIN in example/
|
| 169 |
- add a --enable-pcsclite option (default to yes) so that the driver
|
| 170 |
can be compiled for a different framework (one needing
|
| 171 |
tokenparser.l like Solaris)
|
| 172 |
- Reset action is power off and power on, not just power on
|
| 173 |
- use the include files from pcsc-lite
|
| 174 |
- add a mechanism to allow power on at 1.8V, 3V and then 5V as
|
| 175 |
specified by ISO 7816. We still use 5V for now to avoid problems
|
| 176 |
with non ISO compliant cards
|
| 177 |
|
| 178 |
|
| 179 |
0.4.1 - 14 February 2004, Ludovic Rousseau
|
| 180 |
- distribute missing files readers/supported_readers.txt and
|
| 181 |
src/create_Info_plist.pl
|
| 182 |
'make install' failed because of this.
|
| 183 |
|
| 184 |
0.4.0 - 13 February 2004, Ludovic Rousseau
|
| 185 |
- support of T=1 with TPDU readers. A lot of the T=1 code comes from
|
| 186 |
Carlos Prados towitoko driver.
|
| 187 |
My code is GNU GPL, his code is GNU LGPL so the global driver is
|
| 188 |
GNU GPL
|
| 189 |
- PPS negotiation if the reader does not do it automatically
|
| 190 |
- add support for the Silitek SK-3105 keyboard. It's a USB device
|
| 191 |
with multiple interfaces
|
| 192 |
- use the create_Info_plist.pl script to generate the installed
|
| 193 |
Info.plist from an Info.plist template and a list of supported
|
| 194 |
readers. The Info.plist was too "complex" to maintain by hand
|
| 195 |
since it now contains 11 entries
|
| 196 |
- add support of IFDHCreateChannelByName to avoid wrong reader
|
| 197 |
enumeration. This is not complete if you have multiple _identical_
|
| 198 |
readers. You need to use a > 1.2.0 pcsc-lite version (not yet
|
| 199 |
released at that time)
|
| 200 |
- build but do not install the serial ccidtwin driver by default
|
| 201 |
since it is useless on computers without a serial port or without
|
| 202 |
this reader for example.
|
| 203 |
- read and write timeouts are not symmetric. write timout can be
|
| 204 |
shorter since the reader and card is not supposed to do anything
|
| 205 |
before receiving (write) a command
|
| 206 |
- do not try to find usb.h and other libusb files if
|
| 207 |
--disable-libusb is used. Needed if you only want to build the
|
| 208 |
serial driver. Thanks to Niki Waibel for the patch
|
| 209 |
- add a --enable-ccidtwindir argument to ./configure to specify the
|
| 210 |
serial GemPC Twin installation directory
|
| 211 |
- debug and code improvements and simplifications
|
| 212 |
|
| 213 |
0.3.2 - 4 November 2003, Ludovic Rousseau
|
| 214 |
- src/commands.c: correct a stupid bug that occurs with an APDU with
|
| 215 |
2 bytes response.
|
| 216 |
- Info.plist: add SPR 532 in list of supported readers
|
| 217 |
- parse.c: do not exit if the InterfaceClass is 0xFF (proprietary).
|
| 218 |
It is the case with old readers manufactured before the final
|
| 219 |
release of the CCID specs.
|
| 220 |
- move LTC31 reader from unsupported to supported reader list. It
|
| 221 |
was my f ault since in used odd INS byte in my test applet and odd
|
| 222 |
INS bytes are forbidden by ISO 7816-4 ch. 5.4.2 Instruction byte.
|
| 223 |
Thanks to Josep Moné s Teixidor for pointing the problem.
|
| 224 |
- src/commands.c: comment out the automatic GET RESPONSE part. I
|
| 225 |
don't think it should be in the driver. Maybe in pcscd instead?
|
| 226 |
|
| 227 |
0.3.1 - 23 September 2003, Ludovic Rouseau
|
| 228 |
- add --enable-multi-thread (enabled by default) for thread safe
|
| 229 |
support an APDU multiplexing. You will need pcsc-lite-1.2.0-rc3 or
|
| 230 |
above to use this feature.
|
| 231 |
- add --enable-libusb=PATH option is your libusb is not installed in
|
| 232 |
/usr or /usr/local
|
| 233 |
- honor DESTDIR in install rules (closes [ #300110 ]). Thanks to
|
| 234 |
Ville Skyttä for the patch.
|
| 235 |
- src/ccid.c: do not switch the GemPC Key and GemPC Twin in APDU
|
| 236 |
mode since it also swicth in EMV mode and may not work with non
|
| 237 |
EMV cards
|
| 238 |
- src/ccid_serial.c: complete reimplementation of the Twin serial
|
| 239 |
protocol using a finite state automata (code much simpler)
|
| 240 |
|
| 241 |
0.3.0 - 10 September 2003, Ludovic Rousseau
|
| 242 |
- support of GemPC Twin connected to a serial port. Thanks to Niki
|
| 243 |
W. Waibel for a working prototype.
|
| 244 |
- support of auto voltage at power up if the reader support it
|
| 245 |
instead of forcing a 5V in all cases.
|
| 246 |
- support of APDU mode instead of just TPDU if the reader support
|
| 247 |
it. Thanks to Jean-Luc Giraud for the idea and inspiration I got
|
| 248 |
from his "concurrent" driver.
|
| 249 |
- support of "time request" from the card.
|
| 250 |
- parse: new indentation for more readability of supported features.
|
| 251 |
- switch the GemPC Key and GemPC Twin in APDU mode since they
|
| 252 |
support it but do not announce it in the dwFeatures.
|
| 253 |
- new build process using autoconf/automake.
|
| 254 |
|
| 255 |
0.2.0 - 26 August 2003, Ludovic Rousseau
|
| 256 |
- Works under MacOS X
|
| 257 |
- Info.plist: use an <array></array> for the alias enumeration
|
| 258 |
- Makefile rework for *BSD and MacOS X
|
| 259 |
|
| 260 |
0.1.0 - 13 August 2003, Ludovic Rousseau
|
| 261 |
- First public release
|
| 262 |
