Reroute usb power to double output?

I'm curious if it is possible to reroute the power from 1 USB 2.0 port to the other one...? I have a WD ext HD and the power from one is not enough to get the little thing going. This is very frustrating...! There is the option of adding a Y cable splitting the USB into both ports. I would like to just take the power away from one and add it to the other. Is this possible?
If it is... How might one be able to do this?

Unless you know how to manipulate the data paths and soldering job on the logic board...probably not.
Buy a firewire drive and your problem is solved.

  • USB Power output

    I just bought a portable usb harddrive that gets its power from the usb port. However, the amps are to low to power it. Is there anyway to boost the amp output of the usb port?

    I have a similar problem and have a multitude of portable, bus-powered, usb hard drives. I have found that it also seems to be a formatting issue more than a power issue. While I have an assortment of usb power cables and power adapters for my drives my G4 powebooks don't always recognize them as even existing. Curiously enough a drive that my powerbook can find and access while it is formatted as an NTFS drive (windows XP compatible), it will not find at all if it formatted as FAT32 (PC and Mac compatible) or HPFS (Mac only). This even happens if I am erasing and formatting the drive using the Disk Utility in OSX. It works while in NTFS mode, then when re-formatted and rebooted the powerbook can never find it again. I am kind of wondering if it is a GB limitation in drive size vs formatting in OSX.
    I can say that the spin-up amperages required by manufacturers are a little suspect at times. The same manufacturer that says my notebook doesn't put out the 1A required for the drive to start is the same one that says it can sell me a .5A power adapter to fix my problem and is the same one whose drive seems to work fairly often without any additional power at all. Now I am no math genius but that doesn't seem to add up at all. There is also something to be said for the length of USB cable you are using. Most manufacturers will tell you, and I can also say from experience, that a USB cable longer than about 22 inches will usually require an additional power source for the drive, and that anything getting over 10ft and being bus-powered is unlikely to work. Once you reach that length you really need to include a self-powered USB hub in the serial chain.

  • Apple 5w vs apple 12w usb power adapter?

    Which should i buy for my ipod touch 5 the apple 5w or apple 12w usb power adapter?

    Apple has not said. Unless the charger has a very small output, like less than 500 mA, charging rate is controlled by the iPod.
    The 5G iPod has a 1,030 mA-h battery
    Apple says it charges to 80% in 2 hours
    That would mean a charging rate of about 400 mA/hr neglecting charging efficiency
    So I guess about 500 mA/hr with efficiency included.

  • USB input, built in output

    I'm working with a school who have just bought a roomful of 20" iMacs and a Sennheiser 136 USB headset for each machine. I know the headsets are not at all designed for recording or monitoring but the school decided on those for some reason so that's what they got.
    My problem is this, using the USB adapter you can record from the headset mic but the level on the headphones is too low. I unplugged the headphones from the USB adapter and put that into the headphone jack. In the system prefs I can set the input to the USB headset and the output to built in output. This works fine in GarageBandand and photobooth but not in Logic. In the Logic audio preferences if I select the Sennheiser headset as the device I don't get any sound out of the headphones. If I select either the built in mic or built in input the headphones work fine. Unfortunately I can't just plug the mic jack into the iMacs as it is a line input and the headset needs the power from the USB for the mic.
    Hope I'm not being too stupid and any suggestions are gratefully received.

    So you'll have to setup an "Aggregate device" in the Audio Midi Setup of your Mac combinig the USB and the built in outs of your. Here is a link to a good description of how to do that:

  • Can I use other Apple USB Power Adapters with iPad

    I am looking for a spare  Apple Power Adapter to charge my iPad.  I have an iPad (3rd Generation), which came with a 10W USB Power Adapter, Model A1357, output 5.1V. 2.4A USB Power Adapter.  I have two other Apple Power Adapters 1) iPod Power Adapter, Model A1070, output 13V, .62A Firewire Power Adapter, 2) USB Power Adapter, Model A 1265, Output 5V, 1A,and  3) USB Car Adapter,   Can either of the latter three Power Adapters be used to charge my iPad

    Technically, yes, but they will trigger the 'not charging' because they're not giving out the 10W that your device wants. And charging with them will take significantly longer than the ipad charger.
    I'd only use them as a 'shucks, left my iPad charger at home and I'm in a pinch' situation.
    Your best bet would be to either get another iPad charger, or if you're trying to use one adapter for several devices, use the iPad one for the rest of your stuff.

  • Old Apple USB Power Adapter with new nano

    Hi. I have an older Apple USB Power Adapter (model A1102) that I've been using with an Ipod Mini (bought it with the mini a long time ago). I have a new 3G nano on order. Will this power adapter work with the new nano? Or will I be forced to buy a new one?
    Output from the adapter is 5V - 1.0A
    Thanks

    Since I also converted from a Mini to a 3G Nano, I thought I'd give you a couple of pointers; I probably spent a couple of days preparing my existing mp3 library (and that says nothing about videos).
    1) Make sure all of your mp3's are NOT marked read-only and load everything you want into the NEW iTunes
    2) Work on collecting/saving the NEW things like album covert art and lyrics (I sometimes use the lyrics area to list musicians/personnel)
    3) Re-construct your playlists and SAVE everything (iTunes actually writes back to the mp3 files--that's why you don't want them read-only)
    4) Only then start messing with videos, because they tend to crash iTunes depending on your hardware, OS, etc. (for example, iTunes doesn't work well with Vista). My best advice for videos is use a 3rd party converter (like Nero Recode) to ensure iPod format compatibility; don't even waste your time with iTunes for anything that isn't a downloaded/purchased item.

  • Can I save $ while integrating my IPhone? Can I use my BB USB Power Adaptor

    I'm extremely happy with my IPhone (3G-16)... but for anyone who doesn't own a lot of Apple stock, or oil futures, times are tight.
    I need a second USB power adapter. Can I simply plug my IPhone USB cable into one of the myriad of plugs which I have without killing my IPhone?
    I've got one from my blackberry days which takes in 100-240V and outputs DC +5.0V---0.5A.
    Apple doesn't list the specs for their power adaptor online, at least not where I can find them.
    My other options are an ac plug to USB which came with my Garmin bike computer and a car charging unit for the Blackberry.
    How concerned should I be about the different levels of power which may come out of plugs from different chinese factories, and is there a place where I can learn what the IPhone needs?

    Using any other type of charger would void your warranty if it damaged the iPhone.
    You can just charge the iPhone while it's plugged into the USB on the computer. No need to have an extra adapter.

  • Technical Specification of the USB Power Adapter

    Hey guys/gals, do you know the exact technical specifications of the "Apple iPod USB Power Adapter"? I want to know its Voltage Input Range, Voltage Output, Power Output (Watts) and Pin Assignment, i.e. which pin is +V, NC and GND. Thanks.

    The USB Power adapter isn't a smart device - much more like a charger: The only way to switch it off, is to unplug it from the A/C outlet.
    But you may leave it pluged into A/C: Nothing will happen except a small consumption of electricity.
    ad 2: You may view a video through your connected TV set, but there will be nothing like a TV menu to select it - if you want this feature you have to buy a 3rd party docking station.

  • Ipod touch 2nd gen usb power adapter model

    i wanna know the model of my usb power adapter that comes with my ipod touch 2nd gen model a1288..it's already erased that's..i wanna know the output ampere and voltage..thank you

    No iPod touches came with a wall charger. You would have had to purchase it separately. As I saidm one with at least 500 ma will work. 1000 ma (1 amp) sime to be standare for phones and iPods.

  • Ipod shuffle 2nd gen does not charge on new 5W USB power adapter

    Hi,
    my perfectly functional ipod shuffle 2nd gen with original dock will not charge with the new Continental Europe 5W USB power adapter, even though the specs of the power adapter include the 2nd generation shuffle. Shuffle will blink orange three times, longer than normal blinking, and then do nothing. probably nothing I can do about it, but worth a note. The US model of the new 5W adapter does not include the 2nd gen shuffle, so maybe it is an error on the apple specs page.
    Maybe the 2nd gen needs more than 5W to charge?

    indeed, it needs the bigger 12 Watt Adapter and the apple site is wrong.

  • IPod Nano (4th Generation) switches on when connected to USB power - shows Menu & hangs (unresponsive to click wheel) - deems off after 5-sec - Switches off after disconnecting from USB Power - syncs with iTunes - Tried 5R's - Problem still persists

    1. The iPod Nano (4th Generation - 8GB) switches on, only when connected to USB power by showing apple logo and displays Menu options thereafter..
    2. However, I can not access Menu as it is unresponsive to click wheel. As a result it is inaccessible to any further use, 
    3. NOTE: it displays "Battery Fully charged" icon on the screen without any "Lock" icon.
    4. After  5-sec to 10-secs the screen deems off.. i.e. goes to sleep mode.. And thereafter would probably remain like that (sleeeping) for eternity!!!!
    5. It Switches off after WITHOUT DISPLAYING any Apple Logo immediately after disconnecting from USB Power.
    6. In other words, it can be switched on only through USB power in spite of battery being fully charged.
    7. Interestingly, it syncs with iTunes. It is recognised in iTunes (Latest version 11+).. Displays on screen all commands Like.. syncronising, connecting, connected,
    8. Allows to add Music, videos like a normal ipod & displays all status information in iTunes.
    9. Read Trobleshooting & Tried all 5R's. Registered, Resetted, updated & Restored to iOS 1.0.2
    10. It is now displaying to select Language in place of Menu options, with no access through click wheel, centre button whatsoever... Problem still persists
    KINDLY GUIDE ME THE SOLUTION. APPRECIATE YOUR RESPONSE in advance...

    "I get the feeling that this is a software issue that could probably be solved quite easily"
    Since you have already tried all the normal troubleshooting solutions, take the iPod to your nearest Apple Store for a *proper diagnosis.* The staff there will be able to confirm if your problem is software or hardware _*at no cost to you.*_

  • New iPod touch 5th generation charger won't work with computers or USB power adapter?

    I just got this charger less than two weeks ago and just yesterday it started saying "This cable or accessory is not certified and may not work on this iPod." It will only work on some occasions, but most of the time it won't. Other times it will show that it is charging, but when I select to "Trust" my computer it stops charging. When I plug it into the USB power adapter, it rarely works (even when I try it in different outlets.) Any way to solve this issue?

    If a non-Apple cable and the place will not take it back then:

  • IPod Nano + USB Power Adapter (+ Universal Dock)

    Hi,
    I've got an iPod Nano and a USB Power Adapter to charge it. Untill a few days ago it went fine, even with my Universal Dock between them. But since 2 days my iPod only charges when I put the Power adapter direcly into the wall plug, but with my Hi-Fi installation I'll have to use it with a multiple socket.
    Does anybody know why and how to get round this?
    Thanks

    possibly a fuse blown in the multiple socket plug?? or even in the power adapter itself

  • Using USB Power Adator in S. Korea

    Traveling to S. Korea and wondering if I can go ahead and plug in my iPhone using the usb power adaptor that came with my iPhone. Of course, I will get a plug adaptor for their odd looking plug ins. I think I remember plugging in my MacBook Pro and iPod no problem last time.
    Any good tips on what features to shut off so ATT doesn't charge me thousands of dollars during my 3 week stay?
    Thanks in advance.

    There is no problem using the adapter in South Korea. It is dual voltage, so it will automatically work for you.
    Have a good trip and enjoy your iphone...
