Part Number: TUSB1064
Hi Sir,
My customer is using TUSB1064 in docking product. There's only two test items failed now:
TD10.102
TD10.112
Lab comment that DFP side is keep polling (in Polling.Active) status and can't get RX.detect through TUSB1064 on time. But general USB3 function is fine. Can we provide letter to waive the questions? Thanks.
Best regards,
Gary Teng
HI Gary,
Can yo send the full protocol trace files? I cannot properly read the images sent.

RX detect will happen before the polling state as per the USB 3.2 LTSSM. Is the LFPS timing out?
If USB is functional then the link must finish the polling state and enter U0.
What is the setup used to capture these protocol trcaes?
Hi Vishesh,
Please check USB 3.2 Gen 1x1 Hub LVS report in link. Thanks for your kindly help.
