NAME

       ftdi_eeprom - Tool for reading/erasing/flashing FTDI USB chip eeproms

SYNOPSIS

       ftdi_eeprom [commands] config-file

DESCRIPTION

       ftdi_eeprom  is  a  small tool for reading/erasing/flashing FTDI USB chip eeproms. It uses
       libftdi to access the chip, so you will need to  have  the  required  permissions  on  the
       device.

       The ftdi_sio module should not be loaded. You can prevent it to be automatically loaded by
       adding it to /etc/modprobe.d/blacklist.

       You have to unplug and replug your device to get the new values to  be  read.   Otherwise,
       you will still get the old values.

COMMANDS

       --read-eeprom
              Read eeprom and write to ‐filename‐ from config-file.

       --erase-eeprom
              Erase eeprom.

       --flash-eeprom
              Flash eeprom.

CONFIGURATION FILE

       The  configuration  file contains a list of key-value pairs which will be used to flash an
       FTDI USB chip eeprom.  Comments start with #. The beginning of such a file might look like
       the following:

              vendor_id=0x0403        # Vendor ID
              product_id=0x6001       # Product ID

              max_power=0             # Max. power consumption: value * 2 mA. Use 0 if self_powered = true.

              ###########
              # Strings #
              ###########
              manufacturer="ACME Inc"                 # Manufacturer
              product="USB Serial Converter"          # Product
              serial="08-15"                          # Serial

       The  example configuration file that could be found in /usr/share/doc/ftdi-eeprom/examples
       is quite well commented so you should be able to use it as a basis.   The  following  keys
       are supported:

       vendor_id
              Set  the  vendor  ID  of  the  device.  This  value  could be entered in decimal or
              hexadecimal  form,  and  should  be  in  the  range   0-65535   or   0x0000-0xffff,
              respectively.

       product_id
              Set  the  product  ID  of  the  device.  This  value could be entered in decimal or
              hexadecimal  form,  and  should  be  in  the  range   0-65535   or   0x0000-0xffff,
              respectively.

       max_power
              Set  the maximum current the device will use, in 2 mA unit. Use 0 if self_powered =
              true.

       manufacturer
              Set the manufacturer string which normally holds the name of the manufacturer.

       product
              Set the product string which normally holds the name of the product.

       serial Set the serial string which normally holds the serial number of the product.

       self_powered
              Specify if the device is self-powered or not. The value should be true or false.

       remote_wakeup
              Specify if the device supports remote wake-ups. The value should be true or false.

       use_serial
              If this value is set to true, the serial string will be used. Otherwise the default
              serial string will be used.

       BM_type_chip
              This value have to be set to true if you are using a BM chip.

       in_is_isochronous
              If set to true this option specify that the input endpoint is in isochronous mode.

       out_is_isochronous
              If set to true this option specify that the output endpoint is in isochronous mode.

       suspend_pull_downs
              If  this  value  is set to true the pull downs are enabled during suspend for lower
              power consumption.

       change_usb_version
              This value has to be set to true if you want to force the  USB  version  using  the
              usb_version key. Otherwise the default USB version will be used.

       usb_version
              Set  the  USB  version of the device. The change_usb_version value has to be set to
              true.

       filename
              Specify a filename if you want to dump the content of the eeprom into it.
