TI_TUSB8041USB3.0 loopback issue on FIO card

Other Parts Discussed in Thread: TUSB8041

Hi

There is an abnormal phenomenon when we use the "Passmask" tool to test USB3.0 loopback on TUSB8041_port4 and it always shows can not detect. We have tried more than 5pcs FIO. You can refer to "Passmask_cannot_detect.jpg". But we can't see this situation when we use the FIO with TC version TUSB8041. Here I also attached the picture of the TUSB8041 silkscreen for your reference, "TI_TUSB8041_silkscreen.jpg". Could you help to check whether you can see the same error at your side? Please also share you thought.
