Linux: XHCI USB3.0 recognition Issues

Other Parts Discussed in Thread: TUSB7320

Tool/software: Linux

Hi,

 

I am having some issues with a TI USB 3.0 hub.

I have a TUSB7320 USB 3.0 hub connected through PCIe.
Three usb storages are recognized at super speed, but I can't get any message when insert or remove to the other four.
When these are not recognized, mx6-pcie-msi and xhci_hcd interrupts are not work.
Could you advice me ?
Software:
Linux Version 4.1.15
Hardware:
i.MX6SX custom board
