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 the USB Port.

Well, for the first time ever in my 2 years of having this IPOD plug for my 5th Gen...I wanted to upload some pics on my ipod, but i plugged the port into the computer and the other part into my ipod, and it said my port had a power surge of some sort. So i can't charge my ipod via computer, but it works in my ipod player (which is my deck that i have in my bedroom to play music through speakers) and it works...And other USB items (i.e webcam) work in any port...So its seems its just the plug.
It all of a sudden worked when i just plugged it in as i wrote this to be sure what it said, but does anyone know why this happened?

When you say "port" do you mean the iPod cable that has a dock connector on one end and a USB connector on the other end? When you have your iPod connected to your iPod player does the player have a dock connector on it such that the iPod plugs directly into the player? If the answer to both of these questions is yes then I would suspect that the iPod cable is bad or on its way out. Another test of the cable would be to connect it to an iPod power adapter that plugs into the wall and see if the iPod charges.
The other possibility is that there are other USB devices connected to your computer and when the iPod is connected the USB ports on the computer are unable to supply sufficient power to all of those devices.

Can a power surge damage the ethernet port?

My internet was working fine, then a storm came in and the lights flickered. Since then my ethernet port says there is no connection even though there is. I have replaced the router and checked the connection and cable on another computer and they work fine, but the imac no longer recognizes my cable plugged into the port, it just says nothing is connected. I have a surge protector on my imac but not on my router, is it possible a charge could have traveled up the line and fried the port?
I can't find any other reason to explain why it stopped working. Does anyone have any tips on getting the ethernet back up and running?
thanks

Yes, that can easily happen if the equipment is not protected in any way.

Power surge error on Hub port

Hi Everyone,
I am getting the following error on my X1 carbon laptop, I tried to change the power on the wireless but i am still getting the error.. Is it any hardware issue .. ? I tried searching on diffrerent blogs but couldnt find a proper solution. Please let me know if anyone has solution for this issue.
Thanks

Try plugging it into a different computer. Also, check for black marks on the charger. If that doesn't work, get a new charger or book an appointment at a Genius Bar.

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 exceeds power limits of its hub port

My ipod stopped working- completely dead- after I got this message from windows---- "POWER SURGE ON HUB PORT A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device."
The troubleshoot showed nothing.
It was the first time I used the port on the front of my computer.
I tried the 5 R's.
Also, I took the USB cable to Best Buy- they said part of the port from the computer had come off inside the ipod port connector.
I have a new cord and a AC adapter. I tried charging on both- still no response.
If the ipod is dead and does not show up anywhere- it doesnt do any good to retry the 5 R's, does it?????
Does anyone know where I can take it to have it checked????

Power surge might have hurt something inside iPod. If under warranty contact Apple. Likely you are stuck though if the port was at fault and not the iPod.

When I connect my MacBook Air to iPads through a powered USB hub the power cord for the hub explodes and trips the fuse on the building. I've tried different iPads, cords, power points to no avail.

When I connect my mac air to some iPads through a powered USB hub for VPP/Configurator, the power point for the hub blows out (tripping the fuse in the building). I've tried different iPads, cords, power points and of course hubs. Also the computer has a habit of shutting down when any type of USB device is removed from it. Does anyone have any suggestions?

I've done some experimenting, and this is what I've found out:
1) The problem persists when I reformatted the USB HDD devices to ExFAT, so the problem apparently wasn't due to NTFS for Mac OS X by Paragon.
2) The problem persists even when BackBlaze is paused, so I don't think that it's due to BackBlaze.
3) The internet cuts out as soon as data begins transferring either to or from a USB HDD device and won't reconnected until I eject and unplug the device.
4) The problem affects data transfers through either USB port.

Has there been trouble with the charger. I am getting to re-order but the one i had the had the power surge and the end was blackened. Not sure if it safe to use the laptop again?

Has there been any trouble with the charger? I am getting ready to re-order but the one i had.... the had the power surge and the end was blackened. Not sure if it safe to use the laptop again? Thanks.

Can you also see blackening in the power jack on the PowerBook? If so, I would be worried that the surge also damaged the computer/
Does the computer run OK on just the battery? If it is working on battery power, that limits the number of things inside the computer that could have been fried.
If the computer is severely damaged by the surge, it's not worth repairing. However, a couple of posters in Apple forums said their homeowners'/renters' insurance paid them replacement value of their computer after power surge damage due to known problems on the grid, like the huge power outage that hit the SW Untied Stats and part of Mexico yesterday.

Power surge to a USB port

I plugged my brand new iPhone 5 USB cable into my laptop and it displayed a message about a power surge to that port. i dismissed the message and removed the cable. Now none of my USB ports are working.

Are you using an official Apple wall charger and an official apple usb adaptor? Some of the unofficial ones have been known to do that. If it's an official one take it down to the Apple store to get a replacement. If the problem persists it could be related to your phone.

The device was drawing too much power and that the USB port will be shut down

New to forum, help,
Cannot add a USB hub, powered or not, keep getting message
The device was drawing too much power and the USB port will shut down.

Hi
Is your machine connected to AC power? If not, connect it, and it should work. You may also try resetting the SMC.
If it still doesn't work when connected to AC, then the hub most likely is drawing too much power (i.e you have too many devices connected to it)

How much power can deliver the USB port on AirPort Express?

I am developing an appliance that requieres access to a WiFi router and a power source (UL 60950-1 compliant) of less than one watt (100-200 mA @ 3.3V) to power my own WiFi device, and the AirPort Express can be the right device to solve both problems with minimun overhead. The problem is that I cannot find the specification of the current / power limits of its USB port.
To check if it can provide the usual five unit loads, I tried to charge an iPhone 4, but it fails showing the message "Charging is not supported with this accessory", and an external 2.5" HD which requires 500 mA causes the following message to appear on AirPort Utility:
USB Power
A device connected to this AirPort base station's USB port requires more power than this AirPort base station can provide. Plug the device into a power supply if possible, or connect it to a powered USB hub.
Any insight will be welcome.

Never mind - I tried "rebooting". I hate it how that always works!

Can you turn power off of the USB ports

I have a powerbook g4 800 and it has an external fan that is powered by USB. When I put the computer to sleep and have the power adapter not plugged in, the fan still gets power. So I occasionally have the power completely drained after the laptop was in sleep. Usually I remember to shut off the fan, but it's an extra step that seems like it could be solved by setting something somewhere to power down USB on sleep.

Unfortunately the Mac holds the USB ports in an active state to allow mice and keyboards to wake the machine - I don't know of any way to change this.

Power surge killed ipod?

Well, I have a 30GB iPod classic, worked fine every since a friend gave it to me, battery was getting a bit old, but it worked fine. Well one day I plugged it into my dads computer and a little pop up told me there was a power surge in the USB port, and ever since then, It wont turn on. I plug it into the wall or my computer or anywhere and it wont turn on. I've tried resetting it with the Menu and Select button. I don't know what to do, is it dead, or fixable? I had a lot of stuff stored on there. Thanks in advance.

Did you use the iPod in an unsupported docking system say for a hifi ? If so, you may find that the connecting socket on your iPod is a little slack. Try holding your usb cable on to the iPod with a couple of elastic bands before you plug it into your computer. With iTunes up and running and your iPod connected this way, toggle the hold switch and restart your iPod - does it register now?

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.
