       reader.conf - configuration file for pcscd readers' drivers

       The /etc/reader.conf.d/reader.conf file contains configuration
       information 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.

       The /etc/reader.conf.d/reader.conf is a regular text file. Each reader
       must be defined by four fields:

        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 FreeBSD.

       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       and has been superseded by "DEVICENAME".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/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
