ftdi-eeprom is a specialized utility designed for programming the Electrically Erasable Programmable Read-Only Memory (EEPROM) of FTDI (Future Technology Devices International) USB chips. These chips are commonly used in various electronic devices to provide USB-to-serial, USB-to-parallel, or other USB interface functionality. The ftdi-eeprom tool allows users to write custom configuration data to the EEPROM, enabling the modification of device descriptors, vendor and product IDs, serial numbers, and other operational parameters. This is crucial for customizing FTDI-based hardware, ensuring proper device recognition, and tailoring its behavior for specific applications.
