+# This EEPROM configuration is one of two possible configs that can be
+# programmed into FreeCalypso DUART28 adapters (custom hw made by
+# Falconia Partners LLC) based on the FT2232D chip.  The present DUART28C
+# configuration sets a custom USB ID and is intended to be used together
+# with a custom patch to the Linux kernel ftdi_sio driver that applies
+# a special quirk when this USB ID is detected.  The driver quirk in
+# question applies only to FT2232D Channel B and suppresses automatic
+# assertion of DTR & RTS when the corresponding ttyUSBx device is opened;
+# this driver quirk is required in order to use the DUART28C adapter's
+# boot control outputs.
