IPhone causes problems on other USB devices?

Is anyone having problems with external USB hard drives or any other USB peripheral when his iPhone is connected to a Windows PC or sometime after that?
I'm having some problems with external USB hard drives when the Windows system is continuously hammering them for more than a half-hour. The problem is not easily reproducable, and I don't know the cause.
It probably has nothing to do with the iPhone. But one possibility I have to consider is that the iPhone draws enough current (or something else I haven't thought of) that interefers with the USB communications.

What I meant in my previous post was that the USB wouldn't allow the iPhone to draw more current than the USB can safely provide, unless it was defective. I have an external hardrive, a wireless mouse, my printer and my iPhone connected directly to my laptop's USB ports and have not seen any problems with any of them. In several years of using USB devices, I've not seen any problems that I could assign to the USB ports/controllers... they just seem to work all the time. Will be interested as to your findings.

  • Connecting Nano to PC causes other USB devices to unconnect

    Connecting Nano to PC causes other USB devices to unconnect from USB2 ports. USB2 are on a pci card. Is there anything I can do to stop this from happening?

    Hi
    I have Satellite M70-159 and I didnt notice any strange problem with USB ports. I use a few of them like printer, webcam, USB memory stick, optical mouse and external HDD. The devices are recognized properly and I remove them always without safe remove option.
    Now I have Vista preinstalled and till now there is no problem. If I understood you right USB ports are working well but there is problem with USB modem only. Am I right?
    Try also to contact modem producer support. Maybe is issue like this known and hopefully they have some logical explanation.

  • Ejecting iPod causes other USB devices to be ejected at the same time.

    When ejecting an iPod Nano 4g from iTunes under Windows Vista, all other USB devices attached to the computer are also ejected at the same time (external hard drives, thumb drives, scanners, etc.). Is there a way to prevent this from happening?

    Express is slow ethernet.. 10/100 only. The max speed of any connection to a USB hard disk is limited severely by the 100mbit..
    USB is always slow btw.. This is actually a poor way to share a drive. A cheap NAS.. ie ethernet to Sata directly is far far superior and a single disk NAS can be had cheaply.. you will never get close with USB in network situations.
    If you use a hub though, you can plug multiple disks into an Extreme.. I guess the network speed is at least no worse than the USB hub -- ethernet devices which are lousy as a whole.
    Never forget you have the fastest ethernet adapters and fastest possible connectors already on computers on the network.. people are so utterly mesmerized by NAS they forget.. a FW800 or better USB3 if you have a newer computer shared to the network from a computer has much higher throughput and is much cheaper than even the very low end network stand alone boxes.

  • Why is iPhone non-compatible with other USB peripherals?

    So last night what I presumed was a simple update to 6.1.3 turned into 1.5 torturous hours. The reason being that I left my webcam plugging into my PC while doing the update on iTunes. Later on, the phone wouldn't even restore, but once I unplugged the webcam, it went fine.
    Can anyone tell me why iPhone/iTunes has such a problem with copying with other USB peripherals being plugged in? No other USB item I have shows this level of imcompatibility.
    P.

    Because it pulls maximum power from the USB port while most other USB devices do not.

    Java 6 you can't as Apple maintains it, and Java 7 you could if you uninstall it and Oracle provides the earlier version which they likely won't his last update fixed 37 remote exploits.

  • Problem with detecting USB devices.. something abt ehci-hcd??

    Hi All,
    I have a DELL E6410 laptop. I have a problem with connecting USB devices.
    Whenever a power event (such as connecting/disconnecting of AC adaptor) happens, my laptop stops detecting any USB devices and any changes that happen on the USB ports. That is, say an external mouse is connected to the laptop, the mouse stops functioning, and if I connect a mouse/USB_stick or any such thing to the computer, the device is not detected.
    dmesg output show that any connecting/disconnecting events are not detected by the computer. lsusb output too shows the same thing.
    To solve the problem, I need to rmmod the module ehci-hcd and modprobe it back. That is, I have to run the commands rmmod ehci-hcd followed by modprobe ehci-hcd. Then, this problem goes away until the next power event happens.
    This event does not happen all the time, but it happens very regularly.
    Here are the kernel and laptop specs..

    Kindly help me on this issue.
    Thanks

    This is the output of kernel.log when I unplug my AC adaptor with the external USB mouse connected.

    How big is your library?  I would recommend the following troubleshooting steps:
    - Backup your library.  Always a good idea before messing with things.  
    - Create a new library.   Refer to this article for details:  http://support.apple.com/kb/HT1589.  This won't delete your old library, you're just creating a new empty one.  Also refer to this article to get back to your old library later.
    - Add a few albums into this new library.  Not everything, just a small sampling, as a test.
    - Activate Match on this new library.  You shouldn't have to re-pay, it should just say "Add Computer" or similar.
    - At this point, Match should run again. With just a few albums it should complete in just a few minutes.
    If iTunes doesn't crash at this point, then likely there's something about your original library that Match doesn't like - what that is I don't know, but at least you'll know it's not your PC.   If iTunes still crashes, then if could be a number of other things, but probably not your library.   My next suggestion (if you haven't already done this) is to uninstall / reinstall iTunes.   If that doesn't work, then my next ideas you won't like.

  • Problems with multiple USB devices. (Possible Low Power on USB Bus)

    I believe I'm having an issue with the USB bus or one of my devices that I have installed on my iMac.
    I purchased this iMac along with a printer (HP C4280 All-in-One) as part of a promotion deal. I also have wireless logitech USB mouse, and iPhone and an 80gb 5th Gen iPod.
    My problem has to do with syncing the iPod and iPhone. Normally I have the printer attached to the iMac along with the USB mouse. Both devices function as expected. However I have problems when I connect the iPhone or iPod.
    iPod Symptoms: When I connect the iPod the iPod screen shows the flashing red circle with a line but iTunes never launches and the iPod never syncs.
    iPhone Symptoms: When I connect the iPhone the iPhone screen says Sync in Progress and iTunes does show the iPhone in the list of devices but a dialog appears giving me one of two messages (that I've seen so far) - [msg 1] Your iPhone is corrupt please disconnect then reconnect to restore. [msg 2] iPhone device timed out.
    I've been dealing with this problem for a couple months and found that if I disconnect the printer (HP C4280) then connected either other device then everything works just fine.
    I downloaded XCode 2.5 and launched the USB Prober utility. Then plugged in each device in turn and found some interesting findings.
    When connecting the iPhone (1st attempt) the USB Logger reported; (iTunes displayed msg 1 from above)

    1809.166 [1] AppleUSBEHCI[0x28a7000]::Found a transaction which hasn't moved in 5 seconds on bus 253, timing out!
    I'm suspicious of the USB Low Power Notice. If this is true then I suspect the my iMac might need some type of repair. However I am also suspicious of USB Device violating the USB Spec Error. Although this is the message that appears when I plug in the iPhone or iPod I don't think I can assume that error relates to the iPod or iPhone. The error doesn't specify which USB Device is in violation.
    My current workaround is to unplug the printer every time I sync the iPhone or iPod which is cumbersome. I'm also worried that repeated connecting/disconnecting of USB plug for the printer will over time damage the USB port.
    I'm not sure what options I have here. Can anyone provide some suggestions or information that might provide some insight.
    Best Regards,
    xgnomex

    A-Ha! Now I'm feeling like my 1.5 hours of reading this forum are not wasted, since I've found others with similar symptoms.
    I've only had my iMac for two weeks today. I've got some new accessories & have experimented with the ones I've had awhile (various USB external drives). My model has 3 USB ports, one of which is taken by the keyboard, of course.
    Over the weekend, I picked up an MS Office 2008 Upgrade and also an HP Officejet Pro L7680 all-in-one. I only mention the Office upgrade because I installed it on the same day as the printer, but it's possibly unrelated.
    I actually have a Belkin 4-port hub--not the same one suggested in this thread, but externally powered with it's own A/C adapter. (It's a Hi-Speed USB 2.0 r-Port Hub, model F5U234 Rev.3, and I used it with a previous iMac G3 CRT with no problem.)
    So with a LaCie 100 GB USB Mobile Drive in one of the iMac's ports, and the HP L7680 in the iMac's third port, or the HP via the Belkin hub in iMacs the third hub, here are some of the symptoms I've seen:
    1) while browsing in Firefox, suddenly the mouse-cursor will "freeze" (get stuck) in a pull-down selector...sometimes it unfreezes, but eventually (like on the next pull-down menu) the keyboard & mouse will shut off (and if you wait & the iMac goes to sleep, the keyboard won't let me enter my unlock password when I wake the iMac with the Apple Remote)
    2) when trying to open a document from the LaCie in MS Word, Word freezes and the keyboard & mouse go dead--terminal beachball--to restart the computer, I have to hold in the power button
    3) when trying to print a message in Mail, Finder freezes (though the print job does finish)
    These symptoms seem strange! Hey, it's just supposed to work, right? But everything has limits, so my question becomes, "how much stuff can I hook up at once?"
    I wonder if this Apple article is addressing this issue:
    http://docs.info.apple.com/article.html?artnum=25243
    especially when it says "Two high-bandwidth devices or two isochronous devices cannot be connected to a single Universal Serial Bus (USB)."
    So only two hi-speed USB devices can be connected "to the same bus" simultaneously? I'm not entirely sure I understand what "isochronous" means, but I'm thinking I need to peel my printer off the USB somehow, maybe via Airport Express--?
    Does anyone know for sure about USB limitations? Thanks.
    Also, xgnomex, how/where did you find that "USB Logger"? Is that something iPhone-specific, or is it an OS X log in a Library somewhere?

  • HP Laserjet 1022 and Other USB Devices

    Hi All,
    I have an issue with a HP Laserjet 1022 printer and a HP Pavilion A145.uk desktop computer.
    When the printer is connected to the computer it all works fine, when I try to insert a Kingston flash drive all I get is a message saying USB Device not recognised.
    I have tried installing the lastest drivers for the printer on the computer but I still get the issue and it becoming very annoying.
    I have searched the internet and tried all of the registry 'hacks' to try and resolve this but its still an issue.
    Thanks
    Rob

    Rob,
    The problem is with the cable.
    I had a similar problem for about 2 years where my LJ 1022 would only work with a single Windows XP PC I had.  It would not work with the new vista PC I got. I kept getting "usb device not recognised" whenever I tried installing the printer. I thought that it was a problem with the Vista software drivers but when my Windows XP machine died and I tried unsuccessfully to get it to work with 3 other XP machines I realized that it wasn't the operating system.
    HP Tech Support and all the forums I found kept telling me to upggrade the drivers and download this and that. None worked. I found a note from one other person facing similar frustrations that indicated that his USB cable was going bad and he decided to replace it - only to find that the printer refused to work with the new ones he got. His last entry was that he was going to get a serial cable from HP. I think this is your best bet.
    I tried another usb cable I had (no lable on it) and it has been working perfectly ever since. I have now tried it on about 4 PCs (XP & Vista) and it works on all. I don't know what it is but there is some difference among USB serial cables - which I intend to find out. 
    Try the cable my friend and let me know how it goes.
    Cheers,
    Daniel

  • Wierd problems, says the USB device not recognized

    I have a 5 generation iPod, bought it Christmas, worked fine until two weeks ago, then whenever I connect it to my computer it sort of "works" for 5 seconds, then windows says "USB device malfunctioned, object not recognized" then the iPod freezes...
    Can anyone help me?

  • TM causes problem on other partition of split drive

    I have a LaCie 320 d2 which is partitioned with 120GB for Time Machine and the rest for general storage. All goes well on the TM side, but the remaining partition has had problems twice now.
    The symptoms are the general area being unable to accept any more data, giving the error that the current file is in use. It doesn't matter what type the file is, or how large. When it reaches its limit, it will clunk a few times and stop with an error message.
    The latest time happened when I was transferring a folder containing 11GB of mixed files from my desktop to the general area. I left it to get on with it, but while I was away TM started to backup, including the 11GB folder on my desktop. This leads me to believe that TM was trying to read the file at the same time as Finder was copying it. Whatever problem it encountered was left on the HD and stops it from writing any more data.
    I can't remember whether there was a similar 'double copy' scenario the first time. The problem can be fixed only by erasing the drive entirely (one partition only doesn't help) then repartitioning and restarting TM.
    I do have other storage, on the network, so if the problem occurs again I will leave the whole drive as TM. I'd rather not, as a FW drive is very handy to have.
    If anyone has had any similar problems or knows how the problem is caused/might be solved, please let me know.
    Many thanks.

    Welcome to the Apple boards.
    Do you have TM set to backup the other half of the external drive? That might cause an issue.
    I would suggest doing your copying right after TM ends a backup. While LaCie drives are quite good, you are really asking it to multitask if you are copying a file to it while TM is trying to backup both the original file and the one being copied. You may find that some of your files are locked and marked open which can cause problems.
    Delete any files that were being copied during this process and recopy them, unless you have already deleted the original, in which case you might find it on TM, in which case you can copy the TM backup onto your internal drive and then over to the other partition after removed the bad file.
