       reader.conf - configuration file for pcscd readers' drivers


       The  /etc/reader.conf.d/*  files  contain  configuration information for serial and (some)
       PCMCIA smart card readers.

       USB readers SHALL NOT be configured using these files.  pcscd uses  another  mechanism  to
       automatically load USB drivers.


       The  /etc/reader.conf.d/* files are regular text file. Each reader must be defined by four

        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 handler 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

       The "LIBPATH" field is the filename of the driver code. The driver is a dynamically loaded
       piece of code (generally a*  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       superseded by "DEVICENAME".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.


        # Gemplus GemPCTwin reader with serial communication
        # connected to the first serial port
        FRIENDLYNAME      "GemPCTwin serial"
        DEVICENAME        /dev/ttyS0
        LIBPATH           /usr/lib/pcsc/drivers/serial/
        CHANNELID         1


       In order to set up your /etc/reader.conf.d/my_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.
