USB device set address failure

[Upakul Barkakaty]

Hi all,

I have been facing a Set address failure when I connect a USB to the host
which is connected on the PCI-Express bus(connected through a Pci-to-Pcie
bridge). When I try out the same thing on a USB host connected to a PCI bus,
then it works fine.

Heres a snapshot of the log:
