TUSB322I: The CC state is always read by default state

Part Number: TUSB322I
Other Parts Discussed in Thread: TUSB322

Hi team,

One of our customer's issues, I'm forwarding it below, could you please provide some troubleshooting suggestions

The test symptoms are as follows:
1. Without inserting any device, the register value of the TUSB322i read on power is (0~0x10): 32 32 33 42 53 55 54 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0000

2. As the host, insert the USB flash drive and read the register value of TUSB322i as (0~0x10): 32 32 33 42 53 55 54 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00,
In turn, the readout register value is unchanged.

3. As a slave, connect to the 3.0 port of another USB host device via the data cable, we cannot see our usb device on this device.
The register value of the TUSB322i read is (0~0x10): 32 32 33 42 53 55 54 00 0e f0 00 00 00 00 00 00 00 00 00 00 00 00 00,
In turn, the readout register value is unchanged
