I am reading the datasheet of TUSB4020BI-Q1 and got a bit confused with the device initialization.
Basically, what I need is, a standalone USB hub without any external I2C EEPROM and external host SMBus programming. There is an application example in the datasheet which says it requires no I2C EEPROM. However, in the programming section, it also sounds like that if the I2C EEPROM is not programmed correctly, the USB hub will not work.
My thought would be that, if there is no I2C EEPROM, the chip will load all the default settings and behave like a standalone USB hub. Is it correct? Or I have to use external I2C EEPROM or external host to initialize it via SMBus?
