Hello I=E2=80=99m stuck in the very same situation in an exactly same scenario. I= =E2=80=99m using =E2=80=9CEmerson Networks mvme7100=E2=80=9D board that contains the Free-sc= ale MPC8641d processor. The setup is exactly same as mentioned i.e. [PowerPC controller]<-->[PCI Express]<-->[PCIe-to-PCI bridge]<-->[PCI USB Card]<-->USB Device =20 And I=E2=80=99m getting SET_ADDR_FAILED error. I tried to debug this furthe= r at my end and found this was perhaps due to interrupts not coming from the USB controller. And yes, I verified that it works as expected in X-86 setup. Also, the same USB controller works fine if I have PCI instead of PCI Express in my setup.=20 My QUESTION: IS this a known issue? Or any other developer facing the same issue? Any suggested work around for the same? Cheers!! Neha Oberoi wrote: >=20 > Hi all, >=20 > I am facing a strange problem with my freebsd stack. I am using freebsd > version 6.0.
