How to combine the USB2.0 with USB3.0 for a standard USB3.0 interface?

TX2 supports 3 USB2.0 and 3 USB3.0(USB2.0 PORT#0,#1,#2,USB3.0 Port#0,#1,#2).
The USB2.0 signals are D+/-, USB3.0 signals are RX+/- and TX+/-,and the standard USB3.0 signals are D+/-,RX+/- and TX+/-.
How to combine the USB2.0 with USB3.0 for a standard USB3.0 interface?
USB2.0 PORT#0 combine with USB3.0 PORT#0,USB2.0 PORT#1 combine with USB3.0 PORT#1,…and so on?
Or can we combine USB2.0 Port#0 with any USB3.0 port?
Where can I config it?
TKS!

Hi Trumany,thanks for your reply.
I have read Chapter5.0 USB,PCIe&SATA of OEM DG,but the description about USB configuration is not very clearly for me .
1.Where can I config the Lane mapping configurations(Page 20 of OEM DG,Table 15,Total 6 modes,and the carrier board selcets the 2nd mode)?
2.How to combine the USB2.0 with USB3.0 for a standard USB3.0 interface?Are there any other documents descripting about it?
