17 * @brief This provides reader specific low-level calls.
18
19The routines specified hereafter will allow you to write an IFD handler
20for the PC/SC Lite resource manager. Please use the complement
21developer's kit complete with headers and Makefile at:
22http://www.musclecard.com/drivers.html
23
24This gives a common API for communication to most readers in a
25homogeneous fashion. This document assumes that the driver developer is
26experienced with standards such as ISO-7816-(1, 2, 3, 4), EMV and MCT
27specifications. For listings of these specifications please access the
28above web site.

30@section UsbReaders USB readers
31
32USB readers use the bundle approach so that the reader can be loaded
33and unloaded upon automatic detection of the device. The bundle
34approach is simple: the actual library is just embedded in a
35directory so additional information can be gathered about the device.
36
37A bundle looks like the following:
38
39@verbatim
40GenericReader.bundle/
41  Contents/
42    Info.plist  - XML file describing the reader
43    MacOS/      - Driver directory for OS X
44    Solaris/    - Driver directory for Solaris
45    Linux/      - Driver directory for Linux
46    HPUX/       - Driver directory for HPUX
47@endverbatim
48
49The @c Info.plist file describes the driver and gives the loader
50all the necessary information. The following must be contained in the
51@c Info.plist file:
52
53@subsection ifdVendorID
54
55The vendor ID of the USB device.
56
57Example:
58
59@verbatim
60    <key>ifdVendorID</key>
61    <string>0x04E6</string>
62@endverbatim
63
64You may have an OEM of this reader in which an additional @c <string>
65can be used like in the below example:
66
67@verbatim
68    <key>ifdVendorID</key>
69    <array>
70      <string>0x04E6</string>
71      <string>0x0973</string>
72    </array>
73@endverbatim
74
75If multiples exist all the other parameters must have a second value
76also. You may chose not to support this feature but it is useful when
77reader vendors OEM products so you only distribute one driver.
78
79
80The CCID driver from Ludovic Rousseau
81http://pcsclite.alioth.debian.org/ccid.html uses this feature since the
82same driver supports many different readers.
83
84@subsection ifdProductID
85
86   The product id of the USB device.
87
88@verbatim
89   <key>ifdProductID</key>
90   <string>0x3437</string>
91@endverbatim
92
93@subsection ifdFriendlyName
94
95   Example:
96
97@verbatim
98   <key>ifdFriendlyName</key>
99   <string>SCM Microsystems USB Reader</string>
100@endverbatim
101
102@subsection CFBundleExecutable
103
104   The executable name which exists in the particular platform's directory.
105
106   Example:
107
108@verbatim
109   <key>CFBundleExecutable</key>
110   <string>libccid.so.0.4.2</string>
111@endverbatim
112
113@subsection ifdCapabilities
114
115   List of capabilities supported by the driver. This is a bit field. Possible values are:
116
117- 0
118  No special capabilities
119- 1 IFD_GENERATE_HOTPLUG
120  The driver supports the hot plug feature.

170
171@section SerialReaders Serial readers
172
173Serial drivers must be configured to operate on a particular port and
174respond to a particular name. The @c reader.conf file is used for this
175purpose.
176
177It has the following syntax:
178
179@verbatim
180# Configuration file for pcsc-lite
181# David Corcoran <corcoran@musclecard.com>
182
183FRIENDLYNAME  Generic Reader
184DEVICENAME    /dev/ttyS0
185LIBPATH       /usr/lib/pcsc/drivers/libgen_ifd.so
186CHANNELID     1
187@endverbatim
188
189The pound sign # denotes a comment.
190
191@subsection FRIENDLYNAME
192The FRIENDLYNAME field is an arbitrary text used to identify the reader.
193This text is displayed by commands like @c pcsc_scan
194http://ludovic.rousseau.free.fr/softwares/pcsc-tools/ that prints the
195names of all the connected and detected readers.
196
197@subsection DEVICENAME
198The DEVICENAME field was not used for old drivers (using the IFD handler
199version 2.0 or previous). It is now (IFD handler version 3.0) used to
200identify the physical port on which the reader is connected.  This is
201the device name of this port. It is dependent of the OS kernel. For
202example the first serial port device is called @c /dev/ttyS0 under Linux
203and @c /dev/cuaa0 under FreeBSD.
204
205If you want to use IFDHCreateChannel() instead of
206IFDHCreateChannelByName() then do not use any DEVICENAME line in the
207configuration file.  IFDHCreateChannel() will then be called with the
208CHANNELID parameter.
209
210@subsection LIBPATH
211The LIBPATH field is the filename of the driver code. The driver is a
212dynamically loaded piece of code (generally a @c drivername.so* file).
213
214@subsection CHANNELID
215The CHANNELID is no more used for recent drivers (IFD handler 3.0) and
216has been superseded by DEVICENAME.
217
218If you have an old driver this field is used to indicate the port to
219use. You should read your driver documentation to know what information
220is needed here. It should be the serial port number for a serial reader.
221
222CHANNELID was the numeric version of the port in which the reader will
223be located. This may be done by a symbolic link where @c /dev/pcsc/1 is
224the first device which may be a symbolic link to @c /dev/ttyS0 or
225whichever location your reader resides.

373/**
374This function is required to open a communications channel to the port
375listed by @p DeviceName.
376
377Once the channel is opened the reader must be in a state in which it is
378possible to query IFDHICCPresence() for card status.
379
380@ingroup IFDHandler
381@param[in] Lun Logical Unit Number\n
382  Use this for multiple card slots or multiple readers. 0xXXXXYYYY -
383  XXXX multiple readers, YYYY multiple slots. The resource manager will
384  set these automatically. By default the resource manager loads a new
385  instance of the driver so if your reader does not have more than one
386  smart card slot then ignore the Lun in all the functions.\n
387  \n
388  PC/SC supports the loading of multiple readers through one instance of
389  the driver in which XXXX is important. XXXX identifies the unique
390  reader in which the driver communicates to. The driver should set up
391  an array of structures that asociate this XXXX with the underlying
392  details of the particular reader.
393
394@param[in] DeviceName Filename to use by the driver.\n
395  For drivers configured by @p /etc/reader.conf this is the value of the
396  field \ref DEVICENAME.
397  \n
398  For USB drivers the @p DeviceName must start with @p usb:VID/PID. VID
399  is the Vendor ID and PID is the Product ID. Both are a 4-digits hex
400  number.
401
402Typically the string is generated by:
403
404@code
405printf("usb:%04x/%04x", idVendor, idProduct);
406@endcode
407
408The @p DeviceName string may also contain a more specialised
409identification string. This additional information is used to
410differentiate between two identical readers connected at the same time.
411In this case the driver can't differentiate the two readers using VID
412and PID and must use some additional information identifying the USB
413port used by each reader.
414
415- libusb
416
417  For USB drivers using libusb-1.0 http://libusb.sourceforge.net/ for USB
418  abstraction the @p DeviceName the string may be generated by:
419
420  @code
421  printf("usb:%04x/%04x:libusb-1.0:%d:%d:%d",
422    idVendor, idProduct, bus_number, device_address, interface)
423  @endcode
424
425  So it is something like: <tt>usb:08e6/3437:libusb-1.0:7:99:0</tt> under
426  GNU/Linux.
427
428- libudev
429
430  If pcscd is compiled with libudev support instead of libusb (default
431  since pcsc-lite 1.6.8) the string will look like:
432
433  @code
434  printf("usb:%04x/%04x:libudev:%d:%s", idVendor, idProduct,
435		bInterfaceNumber, devpath);
436  @endcode
437
438  bInterfaceNumber is the number of the interface on the device. It is
439  only usefull for devices with more than one CCID interface.
440
441  devpath is the filename of the device on the file system.
442
443  So it is something like:
444  <tt>usb:08e6/3437:libudev:0:/dev/bus/usb/008/047</tt>
445  under GNU/Linux.
446
447- other
448
449  If the driver does not understand the <tt>:libusb:</tt> or
450  <tt>:libudev:</tt> scheme or if a new scheme is used, the driver should
451  ignore the part it does not understand instead of failing.
452
453  The driver shall recognize the <tt>usb:VID/PID</tt> part and, only if
454  possible, the remaining of the DeviceName field.
455
456  It is the responsibility of the driver to correctly identify the reader.

516/**
517This function is required to open a communications channel to the port
518listed by Channel. For example, the first serial reader on COM1 would
519link to @p /dev/pcsc/1 which would be a symbolic link to @p /dev/ttyS0
520on some machines This is used to help with inter-machine independence.
521
522On machines with no /dev directory the driver writer may choose to map
523their Channel to whatever they feel is appropriate.
524
525Once the channel is opened the reader must be in a state in which it is
526possible to query IFDHICCPresence() for card status.
527
528USB readers can ignore the @p Channel parameter and query the USB bus
529for the particular reader by manufacturer and product id.

533  Use this for multiple card slots or multiple readers. 0xXXXXYYYY -
534  XXXX multiple readers, YYYY multiple slots. The resource manager will
535  set these automatically. By default the resource manager loads a new
536  instance of the driver so if your reader does not have more than one
537  smart card slot then ignore the Lun in all the functions.\n

539  PC/SC supports the loading of multiple readers through one instance of
540  the driver in which XXXX is important. XXXX identifies the unique
541  reader in which the driver communicates to. The driver should set up
542  an array of structures that associate this XXXX with the underlying
543  details of the particular reader.
