Timing is done by counting CPU cycles, so all interrupts must be disabled while the calibration runs. For low level timing measurements, usbMeasureFrameLength() is called. This function must be enabled in usbconfig.h by defining -USB_CFG_HAVE_MEASURE_FRAME_LENGTH to 1. It is also recommended to call +USB_CFG_HAVE_MEASURE_FRAME_LENGTH to 1.
