Other Parts Discussed in Thread: TUSB7340
Hi,
I have custom board with NXP processor and TUSB7320 with PCIe interface. The usb controller is detected by PCI. Also usb 3.0 hub is getting detected.
But when i plug any device to usb 3.0 ports, its enumeration fails with error -71. I am using linux kernel 3.14.52
Following is the pci config space:

Following is the error:
root~# usb 3-2: device no response, device descriptor read/64, error -71
xhci_hcd 0000:01:00.0: Setup ERROR: setup context command for slot 1.

usb 3-2: device not accepting address 9, error -71
hub 3-0:1.0: unable to enumerate USB device on port 2
Is there any register configuration required from USB controller side for it to work?
