    kernel/usb4bsd: Apply FreeBSD r278503
    This updates the original patch r274918, which had the following
    Don't use the synchronization endpoint unless referenced by the
    isochronous endpoint descriptor used for the data transfers, hence the
    synchronization feature might not be supposed to be supported [yet].
    This makes seamless playback synced with the USB HOST clock work with
    the DN32-USB module for Midas audio systems and possibly other similar
    products from Klark Teknik.
