--- Comment #3 from Hans Petter Selasky <hselasky@FreeBSD.org> ---
In sys/dev/usb/controller/uhci.c try to change:

        /* get acknowledge bits */
        status &=3D (UHCI_STS_USBINT |
            UHCI_STS_USBEI |
            UHCI_STS_RD |
            UHCI_STS_HSE |
            UHCI_STS_HCPE |
            UHCI_STS_HCH);

Into:

        /* get acknowledge bits */
        status &=3D (UHCI_STS_USBINT |
            UHCI_STS_USBEI |
            UHCI_STS_RD |
            UHCI_STS_HSE |
            UHCI_STS_HCPE);

I'm not sure if it helps.
