TUSB4020BI-Q1: probabilistic communication failure

Part Number:TUSB4020BI-Q1

Hi Ti team,

    Our usb hub communication is sometimes good, sometimes bad. We think it could be a power-on timing issue. But our power-on timing issue seems good. Can you confirm that for us?

Blue(GRST),Yellow(3.3V),Green(1.1V)

    Are this three clauses conflict from datasheet, or we get it wrong?
