I'm designing a hub using the TUSB8041 hub . Does the hub work if I don‘t program the EEPROM?

    Hello Shanshan,

    Yes, the TUSB8041 works without an EEROM.  

     Please note:

    • if SMBUSz pin is pulled low, the hub will stay in programming mode until a SMBUS host configures it and clears the cfgactive bit.. 
    • if SMBUSz pin is pulled high, the hub will stay in programming mode if a blank EEPROM is installed. 
    • if SMBUSz pin is pulled high, the hub will read in configuration data if a programmed EEPROM is installed. 
    • if SMBUSz pin is pulled high, the hub will default to pin configuration mode if a no EEPROM is installed. 

    Regards,
