USB upper port can't work in MPC-LS Evaluation Board

Hi Supporter
There are two USB ports in MPC-LS Evaluation Board, when we plug the USB in, the lower USB works directly, the upper has no response.
The shematic for these two ports are the same, so I'm wondering if we need to configure for the upper USB?
Please help to check where is the problem, thank you.

Is there problem for this USB connection under u-boot?
Send dump from u-boot if both USB ports are connected.
Send dump for "lsusb" command on your board if both USB ports are connected.
Is there glow from the D4 and D24 on your board if both USB ports are connected?
Perhaps there is over current for USB on your board.
Have a great day,
Pavel Chubakov
