READER.CONF(5) PC/SC Lite READER.CONF(5)
NAME
reader.conf - configuration file for pcscd readers' drivers
DESCRIPTION
The /etc/reader.conf.d/reader.conf file contains configuration informa‐
tion for serial and (some) PCMCIA smart card readers.
USB readers SHALL NOT be configured using this file. pcscd uses
another mechanism to automatically load USB drivers.
SYNTAX
The /etc/reader.conf.d/reader.conf is a regular text file. Each reader
must be defined by four fields:
FRIENDLYNAME TEXT_STRING
DEVICENAME FILENAME
LIBPATH FILENAME
CHANNELID NUMBER
The "FRIENDLYNAME" field is an arbitrary text used to identify the
reader. This text is displayed by commands like pcsc_scan(1) that
prints the names of all the connected and detected readers.
The "DEVICENAME" field was not used for old drivers (using the IFD han‐
dler version 2.0 or earlier). It is now (IFD handler version 3.0) used
to identify the physical port on which the reader is connected. This is
the device name of this port. It is dependent of the OS kernel. The
first serial port device is called /dev/ttyS0 under Linux and
/dev/cuaa0 under FreeBSD.
The "LIBPATH" field is the filename of the driver code. The driver is a
dynamically loaded piece of code (generally a drivername.so*file).
The "CHANNELID" is no more used for recent drivers (IFD handler 3.0)
and has been superseded by "DEVICENAME". If you have an old driver this
field is used to indicate the port to use. You should read your driver
documentation to know what information is needed here. It should be the
serial port number for a serial reader.
EXAMPLE
# Gemplus GemPCTwin reader with serial communication
# connected to the first serial port
FRIENDLYNAME "GemPCTwin serial"
DEVICENAME /dev/ttyS0
LIBPATH /usr/lib/pcsc/drivers/serial/libccidtwin.so.0.4.1
CHANNELID 1
DEBUGGING
In order to set up your /etc/reader.conf.d/reader.conf file correctly
you may want to have debug messages from pcscd. I recommend you to
start pscsd in the foreground and debug mode using:
# pcscd --foreground --debug
If everything seems OK you can use the pcsc_scan command to print the
list of correctly detected readers and try to get the ATR of your smart
cards.
