USB Devices not getting detected with USB card on PCI express.

Hi all,

I am facing a strange problem with my freebsd stack. I am using freebsd
version 6.0. The set up is as follows:

[PowerPC controller]<-->[PCI Express]<-->[PCIe-to-PCI bridge]<-->[PCI USB
Card]<-->USB Device

When I plug in an USB device it gives a SET_ADDR_FAILED error, and disables
the port.

Now the strange thing is that the same setup with PCIe and USB is working
all right on a x86 setup.

I tried debugging but didnt get any obvious errors. Any pointers in this
regard would be most welcome.

Best regards,
Nehaa

Hello

I’m stuck in the very same situation in an exactly same scenario. I’m using “Emerson Networks mvme7100” board that contains the Free-scale MPC8641d processor. The setup is exactly same as mentioned i.e.

[PowerPC controller]<-->[PCI Express]<-->[PCIe-to-PCI bridge]<-->[PCI USB Card]<-->USB Device

And I’m getting SET_ADDR_FAILED error. I tried to debug this further 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.

My QUESTION: IS this a known issue? Or any other developer facing the same issue?

Any suggested work around for the same?

Cheers!!
