In one our design, we are using TUSB321 and HDSS3212 to design a DFP USB Type C port with a standard USB 3.0 port as the source. Our schematic is very similar as Figure 4 showed in TUSB321 datasheet (on Page 13). When we test the design, we the DIR output from TUSB321 is always High (about 3.3V) when the plugged USB3..0 device orientation is changed. And we also found that with one plugged orientation the plugged device is recognised as Supper Speed device. On another orientation the same device is recognised as High speed device. Could you please what could I do to debug this issue.
