Usb hub power surge

Hi, can anybody help me on why one of my usb port appears " usb hub power surge" is there a way to replace this usb?
Thanks
Mandum

I have the same problem with my Portege T210 which I just bought barely a week ago. 
Now my USB hubs and my touchpad is totally out of use. 
I wonder if it is because the power voltage incompatability? I am in Malaysia, so it's about 240V, and at the back of the laptop it says DC 19V - 2.37A (what does this mean?)
Mandum, I hope you can tell me whether someone resolved this issue for you.

  • IPod Shuffle (2nd Gen) ruined onboard USB hub (Power surge on hub port)

    A user that I support fried his onboard USB hub on his laptop by plugging in his new iPod shuffle. Before doing this, everything else worked, but now, no USB devices will work.
    When he tries to plug in his wireless keyboard/mouse receiver, it says "Power surge on hub port" as a popup balloon (this is Windows XP Pro) above the system tray. When he clicks on it, it says:
    "A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device.
    (The location of the device is shown in bold type)
    To reenable the port, disconnect the hardware and click Reset. If you click close, the port will no longer function."
    Options: Reset, Close
    Neither resetting the port nor rebooting the computer will resolve this problem. Most USB devices are not recognized at all (Windows does not respond to them and they are shown as Unknown Devices in the Device Manager).
    This affects not only the USB port that the iPod Shuffle was initially connected to, but all the USB ports on the computer.
    From everything that I can tell, the USB hub built into the motherboard is fried and needs to be replaced.
    Has anyone else had this problem?
    Is this something that Apple will admit to and pay for?

    I called Applecare and they claim that an iPod Shuffle could not have done this because it never sends power over USB, but only charges. They said to contact the manufacturer of the computer.
    I am not convinced of this claim, however. Possible defects in the product could still cause this, such as it creating a short circuit and having power channel from the USB hub back into itself.
    This is just off the top of my head, but can any of you think of another explanation?
    The timing of everything working before the iPod Shuffle was connected and nothing working after it was connected lays the blame squarely upon the iPod Shuffle. If there had been an issue with the motherboard or its USB hub, it would have shown up before; other USB devices that draw significant power never triggered such a hypothetical defect.
    If anybody has another idea how the iPod Shuffle could have done this or knows of a way to convince Apple to take this seriously, please let me know.

  • USB HUB POWER EXCEEDED (with mid 2007 iMac keyboard)

    When I connect any USB 2.0 device in the keyboard USB port, windows vista (XP too) shows the follow message:
    "USB Hub power exceeded"
    But when I use the same kind of USB hardware with MAC OS they just run fine, with no errors!
    Is there any way to bypass or correct this error in Windows?

    Here's the basic XP troubleshooting document (from Microsoft) for that one:
    One or more USB devices may not work after you start your Windows XP-based computer
    But I've also seen it produced when a high-power USB device is connected to a low power USB port.
    Are the keyboard USB ports on the iMac low power or high power?

  • MacBook Pro - USB Hub power exceeded / Lost TrackPad / iSight

    Hello
    I have an older 17 inch MacBook Pro - Windows XP
    Generic USB HUB , 1 of three is not working
    Marked with a yellow exclamation mark in Hardware explorer in Windows
    Tried dropping the driver etc
    When I insert just a USB memory stick - says USB power exceeded
    Lost touchpad and iSight camera as well
    Logic Board ?
    - Andrew -

    The keyboard is a hit-or-miss proposition for mounting thumb drives. I've found that some brands of drives are more sensitive to this than others. Does the drive work when you plug into the back of the iMac?

  • Usb hub power supply destroyed while charging ipad3

    We purchased an ipad 3 yesterday. At some point I connected it to my one year-old desktop pc to interact with iTunes. The ipad was at about a 60 % charge when I plugged it into a 2.0 usb hub with it's own 5 volt power supply. The hub was plugged into a 2.0 usb port on the pc. The plug-in power supply is UL approved and rated at .5 amps. Within a few minutes the plug-in power supply blew with a bang and a burning smell. The plastic housing contained the destruction, but was very hot to the touch just after. The usb hub was not damaged and thankfully neither was the 2.0 port on the pc. I have since read that the ipad 3 needs more power than most usb ports can supply to charge properly, but have not found any reports where the power supply on an external hub was destroyed. I thought I should report my experience. We will be using the supplied charger to charge the ipad. To use iTunes I will probably connect the ipad directly to the usb 3.0 port on the pc as I have read 3.0 ports supply more power.

    The hub does not send power out until the computer tell it to.

  • Superdrive USB hub power drawing too much power

    Bought a new Air 1.8 SSD today including the SuperDrive. Powered the new MacBook Air, plugged in the Superdrive, and much to my dismay I get an OSX error indicating the Superdrive is drawing too much power. Net result, the Superdrive fails to mount - not too super.
    Has anyone else encountered this?
    Cheers

    Apple store called me today, the replacement SuperDrive was available. When I was in the store picking mine up, I asked them to verify the replacement worked. It did, so I am good to go.
    While I was in the store, another customer was there for a different SuperDrive problem. His SuperDrive would not accept disks. He'd insert a disk, the drive would not draw the disk in. He received a replacement SuperDrive as well.
    When I left the store they only had one SuperDrive left.
    Later this afternoon I received a call from Apple Care. The Apple Tech person indicated they were closely monitoring roll-out of the MacBook Air and wanted to make sure my problems were resolved.
    I was absolutely stunned by the phone call.
    Imagine the attention to detail needed to effect that kind of person to person follow-up. Early adopters like me expect to run into challenges with first generation products. It comes with the territory when you live on the bleeding edge. I've owned literally dozens of DOS/OS2/Windows computers over the last 28 years, and in all that time I have never received a follow-up call like this.
    I should have switched a long time ago.

  • Power Surge on USB hub port

    I bought a Nano about a month ago. When I first hooked it up to my laptop, it worked fine. Now I can't get it to even connect. When I plug in the USB cable to any of my USB ports (with or without the Nano attached), I get the pop-up on the task bar that says there is a "Power surge on the USB hub port" and that I need to reset the port. I am assuming that there is some setting somewhere that needs to be changed, but I just can't find it in any of the Apple Support pages on the web.
    Does anyone have any ideas for me?
    Thanks,
    Jeff

    Hi - Had the same 'Power Surge on USB' problem - thought it was curtains as I could do nothing to get my 18 month old nano to sync or even charge from my computer. I did however manage to get it to charge from the mains with someone elses charger so I tried their sync cable into my computer and - hey presto! - everything back to normal! Then re-tried my sync cable and again 'Power Surge.....' - so maybe a new cable is the answer - hope it works for you - Good Luck

  • Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port.

    When I attempt to install an external DVD/CDRW I receive the following:
    Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port.
    I am forced to reset.

    I would guess that your external DVD is drawing too much power from the USB port, and could be one of the older units; newer units are usually more power efficient. Such device usually come with a USB cable with two USB connectors that can draw power from two USB ports simultaneously. You may be able to get such cable separately but since the two USB ports are located at extreme ends in the S10, you may want to check that the cable come with the USB connectors with sufficient length to reach both the USB ports simultaneously.

  • IPOD Shuffle not recognized by computer, and caused a  USB power surge

    Device is not recognized by computer, and I tried the listed support recommendations.
    The problem originated when I plugged the IPOD shuffle directly into the computer USB ( not using a hub), and this caused a warning window to appear saying unknown device has caused a power surge to this port, and most be removed. Prior to this event, the IPOD shuffle has worked (with direct contact with computer usb or through a powered highspeed usb hub) without issue for nearly 1 year. Any taker's on this issue? Thanks.

    Hi JBR,
    Go to your control panel and click on Install/Uninstall programs. Scroll down and see if you have multiple versions of the ipod updater installed on your computer. If you do, then uninstall both versions. Reboot your computer.
    Next, go to the downloads page and download/install the 1-10-2006 ipod updater. Once installed, go to your start programs and select ipod updater from there. Plug in your ipod and wait a moment. If it's like mine, it'll recognize your ipod and then you can do a "restore" for a clean format.
    After that, open itunes and life should be good.
    Hope this helps!

  • Power Surge on Hub Port - Nokia E7

    Please help me with my problem with Nokia E7. I have been using it since 4 years and never it gave such problem to me. Whenever i connect it to my PC it says power surge on USB hub. i took it to the technician and he said that the problem was with the problem was with the hardware i.e. the USB port. so i spent a thousand bucks in putting a new USB port and still it shows the same problem. my phone charger and the phone's USB wire doesnt work properly. even a small jerk disconnects the connection.
    please value my time and money ur solutions are welcome !

    AJAKRE001,
    An alternative way to connect your Nokia E7 to a Windows computer is through bluetooth. But I since assume you are also having problems charging the phone so the only recourse is to send it to a Nokia Care Centre for further device evaluation.

  • I am using iphone 5C when I use to data cable to charge it from my laptop I always get an error message saying 'Power Surge on hub port'. I am not able to charge my iphone

    I am using iphone 5C when I use to data cable to charge it from my laptop I always get an error message saying 'Power Surge on hub port'. I am not able to charge my iphone at all. Please help

    I have read that usb hubs usually have only 1 port at a high enough watts = volts x amps iPads need 10watt = 5v x 2 amps so when you use more devices it may share the power so I would buy a usb charger with 2+ amp ports if you want to just charge your devices the computer hub are not designed for that just communication

  • "Power surge on Hub Port" Message

    I had to order a new replacement iPod and when I plugged it into the computer after fully charging it. A "Power surge on hub port" bubble keeps popping up in the bottom left tray. I've tried to follow all of the iPod tutorials but nothing works...any suggestions?
    Thanks for any help

    This sounds like your computers problem then and not apples.
    Adjusted the usb port properties? :s
    If you're using Windows XP, maybe you should try uninstalling the usb ports then re-instaling them
    on the start menu, right click "my computer" then click properties. Choose the "hardware" tab, then click "device manager"
    Scroll to the "Universal Serial Bus controllers" at the bottom. expand it by clicking the + then right click the top usb item and uninstall it. Make your way down the remaining items and uninstall them. ((ONLY THE USB DEVICES!!!))
    Once this is done, right click in the window and "scan for hardware changes". THen right click the usb devices with red crosses and choose the option to click "install" or "update driver"
    This should restore origional settings to the devices and then all should work.

  • Power Surge On hub Port :(

    when i plug my usb cord in. it says Power Surge On Hub Port, can anyone tell me how to solve this problem. it wont allow me to charge or put songs on my iPod. Help is greatly appreciated.

    I have the same Multi-Burner drive, an X61s, and an X61. I don't get this message on any USB port. I also tried plugging it in with an audio CD already inserted so that it would draw power spinning up the disc right away.
    Is it possible that you have other power-using USB devices plugged in, and the Multi-Burner just happens to be the last one plugged in, pushing the power use over it's limit?
    If you get this message when the Multi-Burner is the only USB device plugged in, I think you have a hardware problem.

  • USB power surge??

    Whenever I connect my mini to the computer it comes up with USB power surge balloon and i clicked on it and tried to fix it but that didn't help. i've tried a self powered hub and 3 different cord and reinstalling the software but nothing seems to work....HELP!!!

    Are you plugging into a port directly on the computer or is it on a usb hub? The port you plug into must be powered in order to charge the ipod. If it is a hub then the hub needs to have its own plug in power supply. The ports directly on the computer should all be powered, if the one you are using doesn't work then try a different one.

  • USB Power surge problem on my P35 Neo F

    Hi,
    I finally got my BIOS problems solved and have already installed everything and almost everything is ok with my system...
    BUT. There is still the problem with the "Power surge in USB hub". I don't know whether this is the right forum for this but I'll explain my situation and maybe someone can help, or at least move this to the right forum.
    So, first of all, when trying to do the usb flasher bios update I came across the problem where the computer totally freezes when you put a memory stick to a usb hub. That I cleared by removing the wires leading to the extrenal case usb ports, which weren't working anyhow. After updating the bios, I started working normally and thought that everything is ok with my usb wireless desktop devices and my external HDD connected. Yesterday if I turned the external HDD on, the power surge notification would pop up. Anyhow, today everything was ok until I plugged the HDMI-DVI cable for my 2nd monitor, a LCD Tv, in my computer, after which the power surge notification popped up once again. When I'm using my second monitor, it works ok for about 5 minutes after which the 2nd computer loses the signal and turns itself off. I realised that yesterday I had the same cable contacted so there must be something there.
    Long story short, do YOU think that this power surge has something to do with my Akasa PSU not providing suffient power? That would sound like the most simple solution as when I contact another device to my computer, the power surge occurs, as well as the fact that the 2nd monitor, the LCD TV, turns itself off after a few minutes of signal..
    OR, would it be a possibility to buy an active USB hub, which was suggested to someone earlier, for the HDD drive, which actually has an external power source of it's own. Could the external active HUB be the solution or should I just go and buy a new PSU, which would be a lot more expensive and to be honest, might not even be the solution..
    I must also point out that with my previous computer, the HDD drive, the wireless desktop and the HDMI-DVI cables were always connected at the same time without any sort of problems, so could it even be a problem with the Mobo?
    Sorry for my english if it's unclear, but if someone knows how to help, please do so.
    Thanks!

    Ok, so the best bet is that it's the PSU, I gotta start searching for one then.
    Just to doublecheck, here are the voltages for my psu
    voltage regulation minimum load maximum load  peak load 
    +3.3V        ±5%         0.5A           30.0A            - 
    +5V           ±5%         0.3A           30.0A            - 
    +12V1        ±5%         1.0A           14.0A          16.0A 
    +12V2        ±5%         1.0A           15.0A           - 
    -12V         ±10%         0.0A          0.5A             - 
    +5Vsb        ±5%          0.0A          2.0A            2.5A 
    I have absolutely no idea what the figures mean, so can someone explain me the +12V voltages in this SPU, so that I won't go and buy a new PSU in vain.
    Thanks in advance for your great assistance!
