The TUEB1310 and TUSB1310A PHY_MODE[1:0] pins must be set to 01 to operate properly. The other modes are unsupported and will cause the device to not function.

thank you for your reply

Another question :

How can the link controller know the communication is USB3.0 or USB2.0?

Thanks!

Check out the LTSSM state machine in the USB3 specification. It should first enable its SS RX termination and try to connect for something like 8 tries, then if there is no connection it should disable the SS termination and enable the HS termination and try to connect at HS.
