Devices that communicate using the IEEE 1394 specification can respond to PC requests with a "BusyX" code. In this case, the device is busy, because of hardware limitations or software interactions in early generation of the 1394 chipset.

Support for BusyX retries is defined in IEEE1394-1995 specification and is important for successful computer to 1394 device communications.
