Hi，Elias

I am drawing a schematic using TUSB4020BI as usb hub. It seems TUSB4020BI couldn't connect to upstream port until the configuration is completed, and there is no mcu or cpu to configure it. So I am considering using EEPROM.

Joel.jimenez already sent me a download link of EEPROM program tool through Email.

Thanks for the help

Hello,

If the TUSB4020B has SMBUSz enabled (SMBUS mode), then it will not connect to the upstream port until the hub has been configured by the SMBUS controller. If SMBUSz is not enabled, the TUSB4020B can be configured using EEPROM or using pin configurations if EEPROM settings are not needed.
