XHCI USB3.0 recognition Issues

Question asked by Masaki Hayakawa on Dec 11, 2017



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.
My kernel config is set by i.MX_Linux_Reference_Manual.pdf 40.4 Using PCIe Endpoint and Running Tests.
Could you advice me ?
I've used fsl-yocto-L4.1.15_1.0.0-ga.
