The Cypress EZ-USB family of chips, including models like 2131Q, 2131S, and 2135S, are USB microcontrollers designed for a variety of USB-based applications. These chips are often used for tasks such as USB-to-I2C bridges, USB data storage, USB peripheral devices, and more. They are part of the EZ-USB FX2LP series, which is well-known for offering high-speed USB connectivity and the ability to integrate with external devices, such as EEPROMs for storing data.
In your question, the issue seems to be with a missing EEPROM driver for the Cypress EZ-USB 2131/2135/2131S devices, likely indicating that the EEPROM (which is a type of non-volatile memory chip) is not being recognized by Windows due to a missing or incompatible driver.
