Hi~ TI expert

I would like to design 2port USB3.1 hub module.

But I could't find solution, There is only 2port USB3.0(TUSB8020B) or 4port USB3.1(TUSB8044).

Please let me know how can i design 2port USB3.1 hub.

    Hello Mason,

    We currently have no USB 3.1 hubs with only two ports; although you could use TUSB8041A, TUSB8042, TUSB8043 or TUSB8044 and leave the unused ports floating. If you are willing to get a USB compliance logo on your system, unused ports must be also reported/configured on the device by using an external EEPROM or SMBus master.

    Please note that even though TUSB8041A, TUSB8042, TUSB8043 and TUSB8044 are USB 3.1 hubs, they can only support USB SS Gen 1 (5Gbps)

    Regards,
    Jorge.
