Hi,
From the datasheet, if the first byte of the external EEPROM is not 55h, the TUSB8041 will load the default configurations. But latter is says:
If the hub detected an un-programmed EEPROM (value other than 55h), the hub will enter Programming Mode and a Programming Endpoint within the hub will be enabled.
In the so called 'Programming Mode' will all the ports work as normal? Or it will stop work and waiting for a programming?
Thanks.
