It on an MSI slotA board, AMD-750 chipset (751 [Irongate] and 756 [Viper]). BIOS report teh card with vend:1106, and Dev 3104, 3038, and 3038 (those 2 are the UHCI controllers right?) Any easy way to go back before that change and see? What files from what kernel?
Did some more digging. Built 2.6.9-1.6_FC with CONFIG_USB_DEBUG=y and found an older 2.6.5-1.358 kernel.
With the 2.6.5 kernel, I still see: ehci_hcd 0000:00:08.2: USB 2.0 enabled, EHCI 0.95, driver 2003-Dec-29 hub 1-0:1.0: over-current change on port 1 hub 1-0:1.0: over-current change on port 2 hub 1-0:1.0: over-current change on port 3 hub 1-0:1.0: over-current change on port 4 *****
lsusb lists the idVendor and idProduct as 0x0000 with this kernel for the ehci device and both uhci devices.
But plugging in a device doesn't kill the ehci controller like the newer driver (2004-May-10) does.
So with the new kernel, and DEBUG on. Only loading EHCI (no UHCI to fall back too):

This is strange. I really don't know where to go to figure this out.
