Firewire® (IEEE 1394) and USB (Universal Serial Bus) are two separate high-speed bus technologies that allow multiple devices to be connected to a computer. The two technologies are not integrated, meaning it is not possible to connect a USB device to a Firewire® port directly. A Firewire® to USB adapter cable for transferring digital video (DV) is available from at least one manufacturer, but it can be expensive and difficult to find.

Even if you don't have a Firewire® to USB adapter cable, it doesn't mean that your Firewire® devices are useless if you have a USB port, or vice versa. Several companies do provide dual hubs. This type of device has two ports in a single hub, which may be either external or internal; one port is used Firewire® and one for USB, allowing either type of device to function. The combination hub is actually two separate ports combined into a single form factor for convenience; there is no conversion between Firewire® and USB taking place when you use one of these hubs.

Another alternative is simply to add two separate cards, assuming your computer has enough available slots. Firewire® and USB cards are both coming down in price, and adding whichever one is missing should not represent a major expense.


Both Firewire® and USB are efficient, high-speed bus standards. A Firewire® hub can support a data transfer rate of up to either 400Mbps or 800Mbps, depending on the standard, and a single Firewire® port can connect up to 63 devices and deliver a guaranteed rate of speed to each one. Firewire® is often used for devices that require real-time operation such as audio and video systems because of this guarantee, and it is also used frequently in storage area networks.

USB can connect more devices (up to 127), but supports data transfer rates of only up to 12Mbps. It is more often used for standard peripherals, such as mice, modems, and keyboards. The USB 2.0 standard supports speeds of up to 480Mbps, which makes it more competitive with Firewire®. On 17 November 2008, USB 3.0 specifications were released, with a transfer rate 10 times that of USB 2.0; consumer devices that use this standard were expected to be available by 2010.

If you cannot purchase a Firewire® to USB adapter, using a hub allows you to use devices that are compatible with either technology. Both technologies support Plug-and-Play and hot-plugging (hot-swappable).

If the operation system on your laptop or desktop computers is not compatible with software of your digital camera, then the PC won't be recognize your camcorder and you cannot transfer video from camcorder to PC.

For example ,if your camcorder software just for Windows XP,2000, 98, then this software will not work with Windows 7 or another OS. Your PC will not recognize old software from your camcorder or will download it with errors (not completely download). That is the main problem, not firewire to USB.

A Pinnacle Moviebox is a true firewire to USB converter and provides a solution but it isn't cheap. If your laptop has a PCMCIA slot or a cardbus slot or a 34mm express card slot, you can buy a card with two firewire ports, but make sure you get the correct type of card for your laptop's slot.

This is much cheaper than the Moviebox solution.

In order to transfer video from my mini dv camcorder to my laptop with no firewire input, I run my firewire cable from my camcorder to my dvd recorder then record from camcorder onto a blank dvd (realtime only but does the job)Load said dvd into laptop dvd drive and transfer files from disc onto p.c. Takes time but works every time.

Post 111

I've found a way around this problem. My Panasonic Blu-Ray recorder has DV input so all I needed was a Firewire cable 4-pin to 4-pin from my old camcorder to the recorder. All the editing can then be done on the Panasonic machine with the ease of remote control! Can then be burned to either DVD or Blu-Ray.

My old camcorder also has an S-video outlet (and the recorder has an S-video input) so there's yet another option. The lack of Firewire input on the PC becomes entirely irrelevant!

I have a Mac book pro -- the last years model. I have a fire wire port but my problem is my camcorder is a new hd one but only came with a USB port so I need help as to know what wire I need.

I think I need a FireWire to USB brig/ cable but don't know where to look as there are so many different cables to buy. Can anyone help?

Post 108

If a tape is recorded on a firewire camcorder could it then be transferred to a usb only pc by playing it through a usb camcorder?

the reason im asking is because cheap usb camcorders seem cheap on Ebay, considerably cheaper than usb/firewire "converters" anyway!

Post 107

i was told that by using a firewire connection between my video camera(mini-dv tape) and computer that i can transfer the video from the DV tape by pressing "play" and then "fast forward" on the camera allowing me to download a 60 minute dv tape in about 10 minutes.

is this just a myth or is the high-speed data transfer technique a viable process?

Post 106

Solution #83 is the winner - you can get an ezcap for very cheap on ebay now, I bought a more expensive model (vcap 305 from climax digital) that works with windows 7. Forget firewire, just transfer through AV cables. Not recommended for movie producers but will do fine for DVD quality projects. Thanks for the solution!

I have a Canon DV600i Camcorder and a Panasonic DMR-EX79 hard-drive DVD recorder. I wanted to transfer my captured video onto my DVD recorder and bought a 4pin-4pin male plug from Maplin electronics (as both pieces of kit will support this).

Here's the rub. The Panasonic acknowledged the Canon and asked if I wanted to record to the hard-drive and when I selected it, the Rec button was greyed out and would not allow me to select. A few seconds later it came up with a message about not receiving the proper DV signal properly and took the camcorder from Paused/Play status (into which it had placed it) to Stop status.

I have a USB port on the hard

-drive, should I get a 4-pin to USB cable or 4-pin to S-video cable? (Both these options are available to me)

Also why didn't the 4-pin to 4-pin male cable work? What is the difference between the two cables I have listed above? --from an interested and frustrated lady!

I, too, have a sony dv camcorder and a usb only laptop. I tried the analog method to get digital video to laptop. The picture quality was bad. I found a conversion box that works. The Pinnacle 510-usb does both analog and dv(firewire) conversion to usb2. No quality loss. It even comes with some nice software or you can use moviemaker.

Post 95

@anon1242: I'm wondering the same thing? any loss of quality there?

Post 93

I found a true firewire to USB converter (complete with proprietary conversion chip) but, sadly, it's sold out and the manufacturer has discontinued it. It was designed to allow all of us with camcorders equipped with firewire (or Sony i.LINK) to download to laptops without firewire inputs.

Since USB 2.0 is so much slower then firewire maybe someone should work on a firewire to eSATA converter since laptops seem all have an SATA input now.

I've got four Sony camcorders with i.LINK out and a new Sony laptop with no way to connect.

I have a Nikon Scanner LS-4000 which uses a firewire IEEE 1394 to transfer data to my PC. Recently my PC became unserviceable. How can I connect my scanner to a USB on a laptop now (except macbook)?

Post 91

Microsoft recently added a v1394 set of instructions, somehow embedded in the new sp3 update. this has virtually nullified the firewire usage parameters, changed the speed, etc. Now dv cameras are not recognized on the fire wire bus. there are various hot fixes released by Microsoft, but they don't work. Personally, I'm seeking a fire wire capture device, with its own integral hard drive solution. there must be something out there. as a fall back option, I have a old imac which captures film OK, albeit the problem of getting the captured film from mac to pc, presents other issues.

Post 90

True that there will be loss of quality from an AV out of camcorder capture but some even newer laptop has no ExpressCard slot. For some, the loss of quality can be acceptable if no other option is available. For those converting VHS, D8, and other analog video to MP4 or other digital format, AV out might be the best option. Use of firewire can sometimes be impossible at all.

Post 89

I have observed that transferring video files using a video capturing device through the AV out of a video camcorder results in a tremendous video quality loss. The best way to transfer these files to your PC with no firewire slot would be through an ExpressCard (next-gen PCMCIA) with a firewire slot, that is inserted to a USB ExpressCard slot adapter.

It would be costly but would definitely deliver quality video clips from your camcorder to your laptop.

Post 88

I have the same problem. Solution no. 83 seems the most logical so I bought a USB capture device. Try to search for MYGICA EZgrabber2. Very good product. I use it and works well. Small enough to carry along.

Post 87

I just made a big mistake. I bought a laptop Emachines E 525. Fast processor 250G HD.

It is sealed. It has two USB 2 ports. I have a Canon HD cam that transfers from DV to firewire only.

It works fine with the "floor" computer and a firewire hub.

I do travel with videography my aim, but no way on road to download. I see USB to fire wire but it looks like they have BUS connects, not four wire USB 2.

What if anything, short of just giving up and editing tapes when I get home, can be done?

I just bought a hub put out by IOGEAR from Microcenter. They said it will work with my Canon Optura pi DV video camera. The camera has a 4 pin firewire and goes to a 6 pin FireWire male plug. The hub is a USB 2.0/FireWire mini hub that is suppose to let you run cameras, etc., and has 4 USB and 3 6 pin FireWire jacks and one up link to the computer. it works with my Canon still camera which uses a mini/regular USB. But nothing happens when I plug in my Canon video camera. Any help would be great.

Post 83

The best solution I can think of is this:

Almost all camcorder has an analog AV out (NTSC). Buy a USA video capture device such as Easycap 4 Channel USB DVR Video Capture Adapter #9908 (less than 15 bucks online). Connect your camcorder or VHS player video and audio out through you computer USB and capture them in different format such as MPEG4 for editing or to DVD recorder. They sometimes include video editing software too. Very simple. Problem solved. Please let me know.

I to have the problem of hooking my DCR-TRV33 Digital Sony Cam. I have an XP tower equipped with express card firewire. It will work up to about a minute of capture and then starts to studder. This either with Windows Movie Maker or Video Studio X3.

Sony won't give me an answer, nor will MIcrosoft. I have an old Imac and it is running rock solid. Apparently the newer driver for XP had to be updated to accommodate the newer Sony cams. So the silly protocols start at 800 and jump down to 400 and then it dies.

Anybody have a solution other then buying a new imac or some way to stream my data for the mac to pc or firewire to sata or firewire to ethernet? All of which I can't seem to locate. I have tons of tapes to dub and convert to DVDs. Anybody else suffering? How about solutions! -Steve

Post 78

I too experienced the problem of reduced quality transferring Mini DV footage over via USB. What I did manage to find out is when transferred via USB, the camera or software slightly compresses it with the result of quality reduction.

I did a big wedding for a friend and couldn't work out what was happening, when streamed directly from cam to TV the picture was perfect, but after transferring via USB it was poor.

The answer was to use the Firewire port, no compression and the same quality from source was transferred.

"Why the hell would USB lose out? What difference does connector make USB 2.0 440Mb/s and FW 400Mb/s. If there is every any loss in quality is due to some compression or file conversion going on before it gets to the cable connectors or in whatever is being used (software) to capture...not the transfer method."

Most miniDV camcorders equipped with both Firewire and USB connectors use USB connection only to transfer reduced quality video (or captured photo on their memory card), suitable only for a webcam. Don't know the exact reason, don't even understand.

I doubt you know anything about computers. Yes, it's all 1s and 0s, but they form commands. Firewire devices do not speak USB commands. USB and Firewire are totally different protocols.

Post 73

I have a question that I can't find the answer for. I am planning on recording my PS3's gaming footage with a camcorder via hookups, but to upload it to the pc after recording it calls for connecting the camcorder to my PC via Firewire. One end is suppose to go into the camcorder and the other is suppose to hook up to the firewire slot on the pc.

Well, I don't have a Firewire slot on my pc, is there anything I can do? And if anyone knows of a camcorder that I can do this with that integrates USB to the PC instead of firmware please let me know also. Thank you.

Post 72

Don't get too worried if a mini DV camcorder has analog or digital transfer to the laptop. If no firewire port then use a VCR analog converter from camcorder into the USB on the PC. Cheap - £20 including editing software. Quality of home videos hardly an issue. Everyone enjoys them.

Capture with the same standard using both firewire and usb and you'll see they are the same.

Is it possible to use an external hard drive to 'convert' from Firewire to USB i.e. download from my camera to my external HD using Firewire and then upload to my computer using USB?

I severely doubt that this is possible, however I'm trying to know that exact answer. I can only assume that its not possible because you would need to communicate with the camera directly. Someone please tell me otherwise.

There are two adapters available, depending on the cable used. You can check online. I've seen two adapters: IEEE 1394 6F/4M Adaptor and the IEEE 1394 6M/4F Adaptor. There are probably other sources. I am sorry to see anger and arrogance in the postings.

This is why I hate the internet. That's about the dumbest statement I've come across yet on the Internet which is seemingly filled with an infinite number of "expert" opinions. I don't know what planet you're from, anon60488, but here on earth, in the world of audio recording, the quality and design of things like the conversion circuitry absolutely have an obvious effect on the quality of the recordings produced. If "there cannot be a reduction in quality in the digital world" were true we'd all be using cheap Dell laptops instead of top-of-the-line Macs.

Well, like most people on here i have a MiniDV camcorder and my brand new laptop doesn't have a firewire port! My fault really, as I forgot about using my camcorder.

Anyway, the long and short of it is merely connecting your firewire head to a USB port via some sort of adaptor does work, however you will still experience the quality reduction with the movie footage.

The only solution is if you have a laptop with an expansion slot (PC Card / ExpressCard) to allow you to add a firewire connector. If, like me, your laptop doesn't even have an expansion slot, you have few options available to you. Live with the poor quality footage via USB, or buy a new camcorder. Bummer, I know.

Post 56

There is no USB to Firewire cable. You can buy an external drive that has both usb and firewire connections.

You can buy old Apple G4's very cheaply to get a firewire setup for your DV conversions. Sounds like a lot but its not. From there you can transfer it over using the G4's usb connection.

The new firewire 800 as opposed to the original firewire 400 is included with the new mac books. You can buy a firewire 400 to 800 adapter.

Post 55

yeah that should be possible, all depends on how compatible the format of your camera is.

Post 54

It's a nightmare of mismatched standards that these jerks selling products play. DV camcorders have firewire outputs only, but most PCs and even the new Apple Macbook (13" Aluminum) doesn't have Firewire port as input. So there's no freaking way you can download video files from camcorder to a computer unless your computer has that firewire port.

All the cables sold in market as Firewire - USB doesn't do a squat. I wasted my money, and am resolved with fact that my videos will only stay on cassettes.

I’m an amateur musician and want to purchase an audio/midi interface for my guitar, keyboard and/or mic into a PC (Vista 32). I don’t want to purchase a toy, yet money is keeping me from spending twice the price for a firewire device vs usb.

If I purchased a USB device, is there an adapter or cable that someone could recommend to convert that USB to firewire? Assuming there is, might I be saving money doing it that way? And, if so, what am I gaining anyway? :-)

this article did not answer the question at all. There is one company that did offer a firewire to usb adapter for offloading dv video from a camcorder to a notebook with only usb ports. the adapter was about $150.

There are express card adaptors (34 mm) which can provide usb as well as firewire ports. You can plug in these cards in the express card slot of your laptops and can connect to firewire devices.

Lots of posts on this but no real answer or agreement. Some say no way to use firewire to usb adapter, or media card. Looks like it's impossible to get to Vista and it only would work with Windows XP?

As I understand it one cannot go from Firewire to USB, but can one go from a USB device to Firewire on a PC? I saw a Firewire cable with what look like the mini-connector found on USB devices, i.e.: my JVC HDD camcorder has this mini-connector as does my VHS to DVD VIDBOX. Would this in fact speed up the data transfer or it simply not communicate because of the different protocols?

Post 44

Since Firewire and USB are two totally different interfaces (not only hardware wise but also the protocol) I cannot see how connecting USB to firewire on a electrical level would solve the protocol issue. Firewire uses a kind of handshaking mechanism where USB is master-slave. So how do these hubs handle this? They problably don't I suppose

Hello folks old dino here. Kindergarten level of computer knowledge lol! My question: I have a Canon Camcorder that uses a DV cable to transfer video to a PC, but my PC only has USB ports. It also has an Av cable to view videos on TV. I have Windows Movie Maker, and ROXIO Creator (not sure how updated). I would like to transfer my videos from the camcorder which uses mini DVs and I would also like to transfer standard VHS tapes. I'm a complete idiot so please bear with me. My CPU has Windows XP. My computer is a Dell Vostro 200 it has an Intel Pentium Dual CPU E2160 @ 1.80 GHz processor, and 1.79 Ghz with o.99 GB of RAM.

Post 42

I am in the same dilemma with most of the posts above. I want to import videos from a camcorder with firewire port but only have a laptop with usb ports. Bought a fireware>usb cable and nothing happens when I connect the camcorder to the laptop. Would expect that the cable has a chip that does the conversion since it doesn’t come with an installation disk. Spent the past couple of hours searching for a driver online without luck. I am yet to read of anybody that has success with the cable and am also asking the same question as anon6218, why are sites selling the cable when it does not work? Anybody knows where I can get a driver or something to make it work?

Post 40

doubtful as dual access hard drives (usb/firewire) still have to be written/read to from the connecting device so unless your camcorder has the option to record or transfer data to an external hard drive, there's no way for you to get the data from the camera to the hard drive.

as for you folks trying to use a cable to connect firewire into a usb port, unless the cable comes with the required software drivers (windows doesn't have one built in) you can't do it, simply because firewire and USB are not just about the cable, they're actually compression algorithms, so by plugging a firewire device into a usb slot would be like having a Chinese person trying to speak to a Russian, without an interpreter(which would be the driver) they wouldn't understand each other and you'd get gibberish.

Post 39

okay, so i bought a cord ("Simo" is the brand) that connects from multiple othe cords on one end (including fire-wire 4-pin, most importantly) and then USB and normal firewire on the otherside.

now, the laptop i use does not have a firewire slot on it for some reason, and when we bought a firewire CARD*card* it did not work.

so i bought the multible-cables one, and it still is not registering that there is a camera.

it's making the sounds recognizing a usb being plugged in, but that's it.

does this mean i got ripped off and it really *doesn't* connect firewire to usb?

its got this little box between the bundle of other cords and the two, is this almost like a hub?

Firewire to USB is not possible!!!

if you try to change a 400/800Mbps to 12/480Mbps what do you think will happen??? the data will become corrupt and the devices will be damaged

Also DV (the standard set by sony for digicamera etc) is different to Firefire but has similar standards.

I'd like to connect USB 2.0 devices - through whatever miraculous blackbox - to a Firewire port.

Post 29

The statement " is not possible to connect a USB device to a Firewire port either directly or through the use of a Firewire to USB adapter" is false if we assume the term "adapter" to mean more than a simple cross-wired cable. Several previous posts have correctly outlined how such a conversion could be done. This is also already being done to convert several legacy protocols: Serial->USB (not as simple as one would think and requires chips-on-cable); PATA/SATA->USB; PATA/SATA->Firewire; SCSI->FireWire; etc. Pretty much any USB or Firewire device is already doing similar types of bridging -- Ethernet->USB; WiFi->USB. Unfortunately, as far as i know, no one sells a generic USB->Firewire or Firewire->USB converter -- yet! I'm hoping that at the very least the USB->Firewire video cable mentioned by several above gets Mac OS X and Windows Vista driver support.

"Although there is no such thing as a Firewire to USB adapter ..."


I found two -- visit the "usbfirewire" website or google for "USB to FireWire adaptor" and it should be the first hit. It is a small pod with a normal USB-A male connector on one end, and a 4-pin FireWire connector on the other. If you want to hook a FireWire-only DV camcorder up to a computer that only has USB ports, then this is the adaptor you need. Not cheap, and it is limited to Windows XP, but it does work.

I have a laptop that only has two usb ports and i want to download video from my camcorder but it can only be done with a firewire port which my computer doesn't have I also don't have a slot for a card bus is there any hub that actually works that anyone knows of???

I am using Vista on a new laptop with only usb ports, I would like to connect a firewire from my canon 1d to operate tethered. Please does anyone know if this can be done and if so how, Thank you

About that post above this one: you can add firewire to your laptop by adding a Laptop FireWire Card, connected in the expansion slot. I found one for my levovo laptop, at the ibm site...quite expensive but worth every penny.

I also found a usb to firewire cable

Runs about 120, but says it's guaranteed to work. Guess it must...

Where can i find a dual/usb hub? my laptop doesn't have an express port or a firewire port and thus has no way of getting firewire, however according to this article there are usb/firewire hubs but so far i haven't found any online that does this. ADS DLX-182 Tech Dual Link Hub and the weird LaCie hub were ones i was looking at, however on the bottom of the ADS one it says note: this unit does not convert USB to FireWire or vice versa and i have no clue how the LaCie hubby connects to the computer or if it will connect a firewire device through usb. If anyone knows a device that works can connect a firewire device to my usb port or if anyone knows more about these two devices please respond thanks.

I have a cable that has the DV connector on one end and a USB plug on the other. My computer calls this "an unrecognized device". My computer does not have a Firewire port. Am I wasting my time and four dollars trying to use this cable? Is there any way to use a Firewire to USB cable without any additional hardware?

A USB 2.0 to Firewire adapter does exist. However it only works with Windows XP (does not support Vista of Mac)

I'm a film student who does a lot of editing and I'm even looking into concentrating solely on editing. I have a Lacie external hard drive, but is unfortunately a USB connection. I'd really like to know if there's any way a duel USB/Firewire would allow my hard drive to connect to a computer via firewire. thanks!

There is a firewire to USB (2) connector. You can get one made specifically for cameras and camcorders. It's quite steep but it's better than logging around my dock with my Sony UX ultra mini computer. I'm going to try it tonight if I can capture in real time from the camera to the computer with DVSPLIT. Hope me luck.

have you tried using a card reader? you can pick one up fairly easily and inexpensively, and some are adaptable to read several different types of memory. i had to buy one when my built in computer card reader stopped working, and my usb cable on my camera gave out. it works great!

i have a pc with only usb 2.o ports and camera with only firewire 400. is there a solution?

Post 15

I got an external hard drive on usb, with movies on it, and i got a tv with a firewire input, how would somebody connect the hard drive to the tv?

Hello, why are sites selling USB to 6 Pin FireWire converters if they are completely different technology, and it couldn't possibly work?

Post 12

You say firewire and usb are two different technologies!? How come some sites are selling adapters from firewire(4&6 pin) to usb?

We're trying to import video from the Sony DCR-TRV19 Handycam onto a Mac. Unfortunately, it's not being recognized as a drive. It supposedly works on the camera owner's Mac at home, and did not need any separate software or drivers. I didn't find any Mac drivers for this device anyway when I searched. The owner seems to think the problem is due to the camera needing a firewire cable to import, but the socket is clearly for a USB cable and is marked as such. The owner believes he used a firewire cable to import before and that we need a "USB to firewire" cable. This article claims that no such thing exists, so...can anybody else offer any ideas on what the problem might be?

I have an imac flat screen, the usb ports have been damaged so only the firewire port works, the machine is unusable, can't connect the keyboard or mouse, any suggestions?

Post 9

I have an old iMac, a similar problem to the one above. I have a TV device which requires a USB 2.0 port and I only have Firewire 400 ports and USB 1.1 ports. I need a cable or a hub that will allow me to plug the TV device into it and I need the hub/adapter to plug into my Firewire 400 port. Is there anything out there??

The best way i can think to bridge a firewire to a usb device would be to get the chipset for both a firewire and a usb port and put a piece of flash memory in the middle so that one device can store to the flash memory and the other can read from it, the flash memory will just have to have multiple inputs and outputs on it.

I would like to connect my 16GB flash memory drive to my iMac. The drive is USB 2.0 of course, and my iMac's USB ports are SLOW (USB 1.1). My iMac has a nice juicy Firewire connection (fast) that I would love to plug my 16GB drive into.

Obviously just converting the connection form factors is not sufficient as Firewire and USB protocols are completely different, plus the data rates are different. However, there is no question that such a conversion can be done by means of a "bridge" acting as a broker between the Firewire and USB connections. The broker basically "translates" between the 2 different protocols and does some buffering. This is what the "movibox" mentioned above

is doing.

I have searched for an external device that can act as such a bridge/broker but with no success. Adding a fast USB port to my iMac is not an option; all of it's slots are full. If anyone runs across such a device please post the info here! I'm tempted to build one and sell it as it appears no one is serving this need.

I have a PCMCIA firewire card that allows me to add firewire capabilities to my laptop via the PCMCIA slot.

I also have a PC that does not have a firewire port. The PC has USB 2.0 running WinXP. My question here is can I buy a USB PCMCIA card adapter which I can fix on my PC and use my PCMCIA firewire card with it?

I have recently bought a laptop which has 3 usb port but no firewire port. What should I do to be able to connect my Digital Video Camera to my laptop?

Post 3

In the light of the above, does a pinnacle moviebox work.....the output is usb2.0 and the input either analog video or ilink / firewire / mini-dv using a six pin firewire connection directly to 4 pin dv out from a camcorder. dv in and out are supported and the computer 'sees' the camera which can be controlled from the pc console.... that must be converting something ??????

I don't really know anything about lingo or computers.... but how do I install a "firewire" if I want to take pictures with my camera phone and then download them onto my computer (I don't have a Mac)???

Post 1

Is it possible to use an external hard drive to 'convert' from Firewire to USB i.e. download from my camera to my external HD using Firewire and then upload to my computer using USB?
