This can be replaced by:

        conf.period.ticks = NANOSECONDS_PER_SECOND / conf.period.hertz;

Can be replaced by: "timeout * 125000"

(I don't think the value of  NANOSECONDS_PER_SECOND will change in the
future ;) ).

Can be replaced by:

    usb_bit_time = NANOSECONDS_PER_SECOND / (USB_HZ / 1000);

    usb_frame_time = NANOSECONDS_PER_SECOND / 1000;
