Was /proc/interrupts showing an increasing number for those devices?
The ehci_hcd driver gets a single interrupt when I reattach a device, but nothing happens on the ochi_hcd device. I recompiled a 2.6.11-rc2 kernel with CONFIG_USB_DEBUG on and here is the logs:

When I boot a Fedora kernel (CONFIG_X86_UP_APIC=n), the OHCI device is assigned IRQ3 and the EHCI device is assigned IRQ5. But it still doesn't work with that kernel.

I just put in a Gigabyte GA-K8NF-9 motherboards (nforce4 chipset), and the USB ports are not working. It recoginizes the ports but no devices attached to them (mouse, external hub). These devices worked properly with my previous motherboard. This happens with both 2.6.10 vanilla and 2.6.10-1.1109_FC4 (2.6.11-rc2 based).

I have tried booting with acpi=off and pci=noacpi with no change. Any help would be appreciated.
