TUSB1044RNQEVM: I want to use 2Port (4lane) USB communication.

Part Number: TUSB1044RNQEVM
Other Parts Discussed in Thread: TUSB1104

I tested TUSB1044RNQEVM because I want to design the USB redriver.

But I found the problem.

I don't want to use the USB 1:2MUX, then I want to set the USB 4 lane setting(RX1/TX1,RX2/TX2).

I set the three mode like below

For first setting, USB communication was only available on one side of USB Plug.

For second setting, USB communication was only available on another side of USB Plug.

Fir third setting, USB communication does not work.

Can't this chip do 4 lane USB communication?

Help me.

Thank you.
