    Possibly the OHCI module hasn't been built.
    # zcat /proc/config.gz | grep OHCI
    # CONFIG_USB_ARCH_HAS_OHCI is not set

    In that case you would need the kernel-source and kernel-headers packages.

    Configure the kernel and select OHCI as a module
    # make modules && make modules_install
    Reboot.

    If needed I can provide all the steps to do it tomorrow, sleep badly needed now.
