Hi Team,
My customer seems have the similar issue to the e2e thread "TUSB321 not detecting cable inversion" but TUSB321AI was used already.
They tried 3pcb and all of these DIR didn't change state at all when either CC1/CC2 pulled low.
Could you please advise what might be possible causes and how to resolve it?
USB is not asserted:
CC1 is low:
CC2 is low:

Allan
