USB v Firewire Charging Pin

I have read that the reason the iPhone 3G does not charge anymore on 'older' third party devices (i.e. car docks/ BOSE sounddock) is because the firewire charging pin is no longer used on the iPhone 3G. Now, does anyone know of an adapter that can be purchased that effectively 'swaps' the firewire to USB charging pin? This way, although not perfect, once can simply interpose this adapter between the iPhone 3G and the third party device to at least enable charging!

It appears that someone finally created a converter to allow older firewire-type devices to charge newer iPods/iPhones...

Nano can charge with both 5-12volt? USB vs FIREWIRE charger

Ok.. I know USB produce about 5v and Firewire produce 12v. According to Wikipedia and Apple, NANO can be charged by both USB and Firewire. Does this mean NANO can take any voltage from 5-12v? I also check on back of my NANO it says rated 5-30v so it means it can take up to 30v which is maximum voltage for Firewire. All these makes sense for me but I am not sure.. Let me know if I am correct. THANKS IN ADVANCE.

Makes sense. DOnt know if you're right or not but my wall charger is 12 volts.

USB to FireWire converter cable, will it work?

There are a number of sellers on auction sites selling USB to FireWire (4-pin) converter cables. Will these work with iMovie in respect of connecting my Samsung MiniDV Digital (tape) camcorder? The seller claims they will, but I am skeptical based on what I've read on the internet - so I thought I'd ask the discussions for their advice/experience...?
FYI I'm using a 13 inch Alu MacBook prior to the inclusion of a FW port...

Despite Niel's great suggestion, the bottleneck is the USB connection into the Mac; even though it's possible to plug a FireWire adaptor into that USB/ExpressCard socket, the ultimate connection (..or combination..) has a USB specification.
USB delivers burst of high speed data, not continuous hi-speed data, which is what FireWire offers, and what miniDV camcorders send out. The camcorder won't be able to make proper contact with the Mac at the far end of the chain, so the computer won't "see" the camcorder, and nor will the camcorder be able to tell the computer "here I am, sending you a digital video-&-audio stream".
The connectors will all physically fit together ..just as you can physically pour paraffin (kerosene) into a car's petrol (gasoline) tank ..but that doesn't mean that the car will actually run with a tank full of kerosene ..or diesel fuel, for that matter.

Lightning to 30 pin adapter support firewire charging?

I've got an old iPod interface in my car -- the kind that charged the first gen iPod touch via firewire. Will the new lighting to 30 pin adapter convert firewire charging to USB?

doubt it as it would be as easy for the old charger to do that as the new ligthing
when a feature is removed then it would not make much sense to remove it and then reinterduce it later on with no benefit to the producer of the product

IPhone3G Not Charging, USB vs Firewire, Dock Connector, BMW iPod kit, etc

If find my Mini/BMW iPod kit will not charge my iPhone3G so I did some reading on this problem and here is what I found. There's about a million or more people complaining.
The dock connector specification simply has pins mapped to both the USB and Firewire interface. It has other interfaces as well--like video and audio. Both USB and Firewire include power lines on the interface, USB - 5 volts, Firewire - 12 volts. The power comes from the computer/car/etc to power the devices like an iPod/iPhone.
The iPhone3G is perhaps the first dock connector device that no longer supports Firewire in any form. So if a computer, car, etc, provides 12V power only to the doc connector--the Firewire interface--it will not charge the iPhone3G battery.
It ***** that Apple made this change, but being a hardware engineer, I can undstand the value in dropping support for an unpopular interface and an additional voltage regulation.
There is no use in complaining as this cannot and will not be fixed. Look for an aftermarket adapter.

I haven't received mine yet so i can't say yea or nye.
I took a "Griffin PowerJolt Car Charger for iPhone or iPod (Black)" and modified it to hardwire into my fuse block in my Infiniti G35X. This is just for charging though.

USB to firewire for car charger?

I have a car charger for my iPod that accepts a firewire cable. I'd like to charge my iPhone with the same device. Does someone make a USB-to-firewire adapter I could use? Any chance it would harm my iPhone?

Bumping this once in hopes of getting an answer.

No charging over USB after Using Firewire charging - 5G ipod

After charging two 5G ipods (30 & 60G models) with my sons firewire power adaptor (charging is supposed to be supported for 5G models just not syncing) both iPods have not been able to be charged using orginal USB cable supplied through macbook pro and have to be rebooted each time I want to sync them using USB (but still won't charge at same time).
I tried resetting etc...nothing. My connections now gives warning that "ipod is connected to a low-speed USB 1.1 port....you should connect it to a high-speed USB 2.0 port"... Trouble is all of my macs have usb 2.0 and since using the firewire (as a charger) it now thinks they are all USB 1.1 ports.
I have even disconnected the battery on the 30G model but this did not fix it either.
Any suggestions?

Yes, After 5 hours of charging on my Mac, I plugged it in a brand new PC with USB 2.0 for 3 hours. I even tried reseting the iPod (in case it is a software problem...) When I took the iPod of the PC, the battery level was still at 70% and I still hadn't used the iPod Nano. He just refuses to charge to 100% and won't accept firewire charging. My next step is letting the iPod play for a while (untill batterylevel is red) and then recharging, see if it actually charges.
PS: Could it be that charging the Nano with a firewire adapter messed up anything?

Firewire 4 pin to usb adapter

Hey, I found this solution on the net for those of use who record video to our macbooks, and lost the firewire functionality with the new macbook purchase.
Jim
hey, I had the same problem and found this solution on the ebay.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWNX:IT&item=1302 69228098
do a word search on ebay for "USB 2.0 A Male to FireWire IEEE 1394 4 pin Cable 3 FT"
It's how I found it. I also found this site.
http://www.uxcell.com/usb-male-ieee-1394-pin-firewire-cable-p-27962.html
Looks like this is the manufacturers site. It appears that ebay ships faster. I got one for just over 6 bucks.

That is not a Firewire to USB converter. No $2 cable could perform such a function. The product is solely and only a cable with a standard USB connector on one end and a "mini" USB connector such as is used on most cameras on the other. The reference to "IEEE 1394" on the web site is just flat wrong, or may apply only to Sony camcorders that support capture from the camcorder via USB and use the same jack type on the camcorder for both Firewire and USB connections (if any).
Looks like this is the manufacturers site.
Nope. If you look closely, you'll see that the picture is of Sony product. What may be the same cable can be found, with the correct description, on Sony's own web site here.

Usb or Firewire adaptor that would fit a 25 pin scsi cord?

I have an old Iomega 100 ZIP reader that was compatible with my G3, when my G3 died I had no way to access the zips with my new Macbook Pro, since there is no SCSI port.
Is there an USB or Firewire adaptor I can purchase that will connect to the 25 pin SCSI cord so I can hook up my Zip reader?
If there is not an adaptor, does anyone know how or where I can back up these files to cd's?
Thanks.

Welcome to Apple Discussions!
There is a device here that converts UltraSCSI to FireWire, but the ZIP 100 is not Ultra. It's an expensive gadget.
You could probably find a used external ZIP 100 USB fairly cheap. See:
http://www.amazon.com/Iomega-Zip-100-Portable-Drive/dp/B00000J3Q7
We have one and used it to move all the files we'd put on ZIPs from two old Macs with SCSI ZIP drives to our newer non-SCSI Macs.

Possible to charge pb with usb or firewire cable through ipod charger?

hello,
i forgot to pack my pb charger for my trip. i do have my ipod charger. would it be possible to charge with that by using the firewire to firewire cable or firewire to usb cable? i haven't tried yet for fear of ruining something.
cheers.
powerbook g4 Mac OS X (10.4.1)

USB and Firewire - from the Powerbook is one way traffic - ie the PowerBook pumps power out. It doesn't need to take power from a peripheral such as an ipod so it's not set up to do so.
As for "borrrowing" a supply from Apple, you don't know unless you ask. If you're away from home for a month might it be worth getting someone from home to send it to you?
There are local Apple user groups in major cities, so you could page apple users in those cities to see if you can borrrow a power supply.
Or you might have to bite the bulllet and just buy another - either from Apple, ebay or even Criagslist. You might find a slightly cheaper 3rd part adapter somewhere.
Sorry can't help any more. Good luck.

Nano wont charge or recognize by USB, but will charge by firewire?

I have an iPod Nano. Its not that old cause I have had this issue for a while and I cant really use it cause its got a lot of old music on it. Anyway. I use the same USB cord to charge my iPhone. It is actually the same cable that came with the nano that I use for the phone. The Nano will charge by firewire, but it wont do anything via usb. Is it garbage? If so, why will it still play?

Does the latest Ipod Classic use the same charging pins as the earlier versions?

Does the latest Ipod Classic use the same charging pin positons as the earlier versions as I want to use it in my Audi where my 5th gen Nano will play but not charge as the pin configuration for charging changed from that of the earlier models.

If your 5th gen nano doesn't change, then a new iPod Classic will not either.
The "change" was that older iPods used firewire to charge the iPod. But that's 12volts (the same voltage as a car's battery). Then along came charging by USB, which is 5volts. So car manufacturers who were on the ball, introduced electronics to drop the 12v car battery voltage to 5v and put that 5v on the appropriate USB pins. (I would hope, that by now, every car manufacturer has sorted this out, but of course that doesn't help anyone with an older model car.)
The incredibly obvious - to anyone with technical knowledge - was that one day, Apple would stop the 12v charging method on newer models of iPod. But somehow, a lot of manufacturers of devices that charge iPods failed to see this. (It really was incredibly obvious, believe me!)
It wasn't just car manufacturers who were caught out by this, so were Docking Station devices. I know of one make, where the manufacturer recalled the ones still in shops so that they could re-work them to charge using the 5v USB pins.
In my car, made around 2006, I had an external device fitted so that I could plug my iPod into the car stereo through the Dock Connector. But hey, guess what? That device will charge my iPod Classic, but not my iPod Touch.
A long-ish answer, but hopefully it not only answers the question, but tells you why too.

Ipad is sometimes "not charging" and sometimes charging ..i have to pull out and put tje charging pin many times til i see the icon that it is charging..i have an original ipad charger..and it always takes time for it to charge succesfully

I need ur help..i have to unplug and plug the charging pin to my ipad many times until i cam see the icon on the upper right that ia alrdy charging..i often see 'not charging' message many times before it will charge succesfully..need ur help guys.thanka

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Can I use my old firewire charger with my iPod Touch

I've recently got an 8GB iPod Touch which obviously only came with a USB cable to charge and sync with my laptop.
However, I've also got an old 4th generation 20GB iPod which came with a firewire lead that connects to a firewire mains charger. Can I use this to charge my iPod touch from the mains? Also can I use either the firewire or the old USB cable to connect to my laptop??
Thanks very much.

You can use the firewire charger to connect your Touch to the mains. I use my old one and it works just fine. I suppose you can also use it to charge using your computer though I can't say I've tried. However, as the newer iPods don't have any kind of firewire circuitry, you can't use the firewire cable to sync you iPod.
Best of luck.

Parallel to USB or Firewire Adapter?

I'm trying to find one that works.
I need to connect an Epson Expresson 836XL large format scanner to my Intel iMac. At first I was looking for a USB or Firewire to SCSI adapter, but then thought of this option since my scanner also has a 36-pin Centronics type parallel connector.
I found a possible fit with the SCSI to Firewire adaptor (http://firewireshop.stores.yahoo.net/firfirscsico.html) but am wondering if Parallel to Firewire/USB might be a more viable (and cheaper) option. See here: http://sewelldirect.com/usbtoparallel.asp or http://www.monoprice.com/products/product.asp?cid=103&cp_id=10311&cs_id=1031104&pid=1610&seq=1&format=2
Has anyone done this or know if it is viable? I worry about Mac compatibility.
Thanks.
Kort

Since Macs never had parallel ports, why would the maker create Mac drivers for this scanner? If there are no drivers, simply connecting it would still not allow it to work. And you would actually need two drivers. One for the special adapter to make it pretend to be a parallel port and one for the scanner.
As mentioned, the scanner also has SCSI ports which I had been using under 10.3.9. I had to move to Vuescan at that point since the OS no longer recognized the scanner with the Epson Drivers. I had hoped that using a parallel adapter, my iMac would just see it as a USB or Firewire device. Vuescan recommends the Ratoc SCSI to Firewire converter but I was hoping there might be a less expensive alternative.
