I bought a CY4609 development board and after I got out 24LC128 (EEPROM), CY4609 still works. Why? What does the program do?

Hello,
-Please check if the jumpers J6 and J7 are set to internal ROM mode i.e. both pulled high. In that case, the hub boots from default firmware stored in ROM.
-In case J6 and J7 are pulled high and low respectively, it is set to I2C master mode. Please check the VID, PID of the hub when it enumerates after the EEPROM is removed. Please check the KBA for more details-HX3 Entering Vendor Command Class - KBA226712
Best Regards,
Sananya
