While not a show stopper, this warning is an indication of a fairly
major annoyance. If you insert a USB 1.0 peripheral, and then insert a
USB 2.0 peripheral in any other port, you are likely to only get USB 1.0
transfer speeds from your USB 2.0 peripheral. This race can only be
solved conclusively by always loading ehci before uhci/ohci. Many folks
have forced this sequence in initramfs, but the best solution is in the
kernel (as always).
