The USB 2.0 to FireWire IEEE 1394 4-Pin Data Cable is a passive data cable designed for specific legacy device connections where FireWire and USB compatibility is already supported at the device and system level. This cable features a USB 2.0 Type-A male connector on one end and a 4-pin IEEE 1394 (FireWire / i.LINK) male connector on the other. It is not a protocol converter and does not convert FireWire signals to USB or enable DV video capture via USB. Important compatibility notice (please read before purchasing): • This cable does not convert FireWire to USB • USB ports cannot capture FireWire DV video using this cable • Will not work with FireWire-only DV camcorders for video capture • Requires hardware and software that already support FireWire-over-USB operation This cable is typically used for very specific legacy or OEM applications where the device manufacturer explicitly states compatibility with this type of connection. Key features: • USB 2.0 Type-A male to IEEE 1394 4-pin male • Passive cable – no signal or protocol conversion • Data cable only (no video capture functionality) • USB 2.0 data rate up to 480 Mbps (USB side limitation) • Cable length: 1.5 metres (6 ft) WHAT THIS CABLE IS / IS NOT ✔ Is: • A passive USB ↔ FireWire data cable • Suitable only for niche, device-specific legacy use ✘ Is NOT: • A FireWire to USB converter • A DV video capture solution • Compatible with standard FireWire camcorders for USB capture For DV camcorders, a FireWire capture card or Thunderbolt–FireWire adapter is required.
