Other Parts Discussed in Thread: TUSB8020B

My customer is considering the USB hub because system port require two ports USB2.0 only and USB3.0.
They want to only one USB3.0 port, so there is considering for USB2.0 hub(TUSB4041I) as following.

Could you check this connection work fine?

Best regards,

Hi Sato-san,

No this connection will not work since you cannot split USB 2 and USB 3 interface of a external connector between a USB Host and USB Hub. I recommend using TUSB8020B to create one USB 2 port and and one USB 3/USB 2 port.
