Okay, this is good.

It looks like your .config has CONFIG_USB_EHCI_HCD=y and
CONFIG_USB_UHCI_HCD=y, right?  And it also has CONFIG_USB_EHCI_PCI=m.

That's why you're getting all those error messages.  Change it to
CONFIG_USB_EHCI_PCI=y and the errors should go away.

Thank you, I'll try setting them all to 'y' but right now they are all set as modules 'm'.
Lets see, I'll try it right away.

Sorry Alan, I tried it - no luck. The errors are still shinning bravely at system start...
