============================
|

- MacOS X/Darwin (libusb 0.1.8beta, CVS snapshot. See "Known problems")

Known problems:
|
| 57 |
===============
|

|

All platforms
|
| 60 |
readers enumeration
|
| 61 |
"""""""""""""""""""
|
| 62 |
You may have wrong reader identification if you connect two or
|
| 63 |
more reader at the exact same time.
|
| 64 |
|
| 65 |
The daemon pcscd and the CCID driver do not list connected readers
|
| 66 |
in the same order. The driver has no way to know which reader has
|
| 67 |
been detected as a new reader by pcscd.
|
| 68 |
|
| 69 |
So if you plug two readers at the same time (for example if you
|
| 70 |
start pcscd with two readers connected or if you plug a USB hub
|
| 71 |
with two readers on the hub) you may have this (with two readers
|
| 72 |
foo and bar):
|
| 73 |
- pcscd scans the USB bus and finds a new CCID reader foo and
|
| 74 |
calls the driver
|
| 75 |
- the CCID driver scan the USB bus and finds a new different
|
| 76 |
reader bar
|
| 77 |
- pcscd continues scanning the USB bus and finds the second reader
|
| 78 |
bar and calls the driver
|
| 79 |
- the CCID driver scan the USB bus and finds an unused reader foo.
|
| 80 |
|
| 81 |
Now the reader foo will be called bar by pcscd and bar will be
|
| 82 |
called foo. This may not be a problem if the two readers have
|
| 83 |
the same name. But it is strange to insert a card in the
|
| 84 |
physical reader foo and see pcscd detect the card insertion in
|
| 85 |
the reader he calls bar.
|
| 86 |
|
| 87 |
The solution is to use IFDHCreateChannelByName() instead of
|
| 88 |
IFDHCreateChannel() and specify the USB device to use. But pcscd
|
| 89 |
does not implement IFDHCreateChannelByName() yet. Maybe in the
|
| 90 |
future.
|
| 91 |
|
| 92 |
Another solution is to plug readers one after the other and not
|
| 93 |
at the same time.
|
| 94 |

libusb
|
| 97 |
""""""
|
| 98 |
The libusb does not yet support USB interrupt endpoints. You will
|
| 99 |
notice that the driver will stop working as soon as you insert a
|
| 100 |
card in the reader.
|
| 101 |
A new version of libusb should fix this bug.

History:
|
| 123 |
========
|
| 124 |
|
| 125 |
0.4.1 - 14 February 2004, Ludovic Rousseau
|
| 126 |
- distribute missing files readers/supported_readers.txt and
|
| 127 |
src/create_Info_plist.pl
|
| 128 |
'make install' failed because of this.
|
| 129 |
|
| 130 |
0.4.0 - 13 February 2004, Ludovic Rousseau
|
| 131 |
- support of T=1 with TPDU readers. A lot of the T=1 code comes from
|
| 132 |
Carlos Prados towitoko driver.
|
| 133 |
My code is GNU GPL, his code is GNU LGPL so the global driver is
|
| 134 |
GNU GPL
|
| 135 |
- PPS negotiation if the reader does not do it automatically
|
| 136 |
- add support for the Silitek SK-3105 keyboard. It's a USB device
|
| 137 |
with multiple interfaces
|
| 138 |
- use the create_Info_plist.pl script to generate the installed
|
| 139 |
Info.plist from an Info.plist template and a list of supported
|
| 140 |
readers. The Info.plist was too "complex" to maintain by hand
|
| 141 |
since it now contains 11 entries
|
| 142 |
- add support of IFDHCreateChannelByName to avoid wrong reader
|
| 143 |
enumeration. This is not complete if you have multiple _identical_
|
| 144 |
readers. You need to use a > 1.2.0 pcsc-lite version (not yet
|
| 145 |
released at that time)
|
| 146 |
- build but do not install the serial ccidtwin driver by default
|
| 147 |
since it is useless on computers without a serial port or without
|
| 148 |
this reader for example.
|
| 149 |
- read and write timeouts are not symmetric. write timout can be
|
| 150 |
shorter since the reader and card is not supposed to do anything
|
| 151 |
before receiving (write) a command
|
| 152 |
- do not try to find usb.h and other libusb files if
|
| 153 |
--disable-libusb is used. Needed if you only want to build the
|
| 154 |
serial driver. Thanks to Niki Waibel for the patch
|
| 155 |
- add a --enable-ccidtwindir argument to ./configure to specify the
|
| 156 |
serial GemPC Twin installation directory
|
| 157 |
- debug and code improvements and simplifications
|
| 158 |
|
| 159 |
0.3.2 - 4 November 2003, Ludovic Rousseau
|
| 160 |
- src/commands.c: correct a stupid bug that occurs with an APDU with
|
| 161 |
2 bytes response.
|
| 162 |
- Info.plist: add SPR 532 in list of supported readers
|
| 163 |
- parse.c: do not exit if the InterfaceClass is 0xFF (proprietary).
|
| 164 |
It is the case with old readers manufactured before the final
|
| 165 |
release of the CCID specs.
|
| 166 |
- move LTC31 reader from unsupported to supported reader list. It
|
| 167 |
was my f ault since in used odd INS byte in my test applet and odd
|
| 168 |
INS bytes are forbidden by ISO 7816-4 ch. 5.4.2 Instruction byte.
|
| 169 |
Thanks to Josep Moné s Teixidor for pointing the problem.
|
| 170 |
- src/commands.c: comment out the automatic GET RESPONSE part. I
|
| 171 |
don't think it should be in the driver. Maybe in pcscd instead?
|
| 172 |
|
| 173 |
0.3.1 - 23 September 2003, Ludovic Rouseau
|
| 174 |
- add --enable-multi-thread (enabled by default) for thread safe
|
| 175 |
support an APDU multiplexing. You will need pcsc-lite-1.2.0-rc3 or
|
| 176 |
above to use this feature.
|
| 177 |
- add --enable-libusb=PATH option is your libusb is not installed in
|
| 178 |
/usr or /usr/local
|
| 179 |
- honor DESTDIR in install rules (closes [ #300110 ]). Thanks to
|
| 180 |
Ville Skyttä for the patch.
|
| 181 |
- src/ccid.c: do not switch the GemPC Key and GemPC Twin in APDU
|
| 182 |
mode since it also swicth in EMV mode and may not work with non
|
| 183 |
EMV cards
|
| 184 |
- src/ccid_serial.c: complete reimplementation of the Twin serial
|
| 185 |
protocol using a finite state automata (code much simpler)
|
| 186 |
|
| 187 |
0.3.0 - 10 September 2003, Ludovic Rousseau
|
| 188 |
- support of GemPC Twin connected to a serial port. Thanks to Niki
|
| 189 |
W. Waibel for a working prototype.
|
| 190 |
- support of auto voltage at power up if the reader support it
|
| 191 |
instead of forcing a 5V in all cases.
|
| 192 |
- support of APDU mode instead of just TPDU if the reader support
|
| 193 |
it. Thanks to Jean-Luc Giraud for the idea and inspiration I got
|
| 194 |
from his "concurrent" driver.
|
| 195 |
- support of "time request" from the card.
|
| 196 |
- parse: new indentation for more readability of supported features.
|
| 197 |
- switch the GemPC Key and GemPC Twin in APDU mode since they
|
| 198 |
support it but do not announce it in the dwFeatures.
|
| 199 |
- new build process using autoconf/automake.
|
| 200 |
|
| 201 |
0.2.0 - 26 August 2003, Ludovic Rousseau
|
| 202 |
- Works under MacOS X
|
| 203 |
- Info.plist: use an <array></array> for the alias enumeration
|
| 204 |
- Makefile rework for *BSD and MacOS X
|
| 205 |
|
| 206 |
0.1.0 - 13 August 2003, Ludovic Rousseau
|
| 207 |
- First public release
