USB Hub test application question

Other Parts Discussed in Thread: TUSB8041-Q1, TUSB4041I-Q1, TUSB8041

Hola,

I have a USB HUB test application for TUSB4041I-Q1 (USB2.0) & TUSB8041-Q1 (USB3.0) as below：

If our device have four USB3.0/2.0 port and the Host side have one USB3.0/2.0 port...

Can I use TUSB4041I-Q1 (USB2.0) & TUSB8041-Q1 (USB3.0) as a USB HUB to test our four USB3.0/2.0 by Host side？

    Hello,
    I don't quite understand your implementation, can you post a block diagram?
    The TUSB8041 can work with USB3.0 and USB2.0.
    The USB3.0 Host Controller and any USB3.0 Devices will connect either at USB3.0 or USB2.0 but not both at the same time, so It seems like you only need the TUSB8041.
    Regards
