TUSB8041-Q1: Using TUSB8041-Q1 without I2C

Hello Team,

Thanks for your support.

we want to use TUSB8041-Q1. We will use 3 downstream ports. All of them were for USB3.0.

This device has I2C register, but can we use this device without any I2C communication or without any EEPROM?

Thanks,

Yuta Kurimoto

    Hello,

    Yes, the TUSB8041 can be used without I2C or SMBUS configuration.  If you wish to have the hub report as only having 3 ports, you would need to use I2C or SMBUS to set that in the "port used" register, but it is not functionally required.
