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 error on Hub port

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.

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.

Mac Book Pro Power Adapter with USB charge ports?

Does anyone make a MBP power adapter with 2 USB charge ports? It seems logical to have one power adapter that charge your MBP, iPhone and iPad all at the same time while minimizing the things one would have to carry on travel.

Hopefully!
I said to them "you dont even need to put the ports on the brick itself, put it on that little wall plug adapter thingy... that way if you only want to charge your iOS devices you can leave the brick in the bag!... Fingers crossed and thanks again for the help tjk!
Best,
David

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.

Combo built-in power outlet with USB charging ports...

Are iPhones only fully functional while charging on an OEM plug? We just installed a combination USB charger into our wall and now the touch screen will not work while it is charging? Anyone else have this particular situation? We are using a Legrand Pass & Seymour P/N 340982 Combination USB Charger.

Seems the charger is the issue... I have never personally had an issue with using my device while charging via any accessory/cable/charger.

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.

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!

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.

Anker Powered USB Hub (7 port, usb 3.0) often won't light up (function) after waking Mavericks from sleep

My iMac is 27" (mid-2010) with 8 GB RAM. My only problem is that my new Anker Powered USB Hub (7 port, USB 3.0) often does not wake when computer does. In other words, the power lights remain off following waking the computer from sleep and I must unplug and replug the HUB. I called Anker and they told me that Mavericks has a new "energy saving power mode" that may turn off power to a USB hub. This is most annoying and I hope that Apple can update Mavericks power management to fix this USB issue. Has anyone else experienced this problem? I've seen similar posts from D-Link USB hub owners. Perhaps if this "question" has a response trail, Apple will see it and create a fix.

Hopefully, Apple will monitor this issue and correct the USB power management issue. We'll see what happens with Yosemite.

USB device has exceeded power limits of its hub AND no sound

Yesterday no sound, but worse...Trying to connect to computer to charge gives me the message "A USB device has exceeded the power limits of its hub power. Clicking on the balloon states "A USB device has malfunctioned & exceeded the power limits of its hub port. You should disconnect the device." Plugging into the wall charger states "This accessory is not made to work with iPhone...want to change to Airplane mode..." Is my iPhone dead? Ideas please. Thanks

Hi, Did you every get a reply? I'm having the same issue. The phone was working fine yesterday. Now, the button doesn't work and I can't sync it to restore it because I'm getting the same USB power limit message.

PLZ HLP:A USB device has exceeded the power limits of its hub p

Hi, hope you can help me, and thanks for reading.
I have a Dell Inspiron 500 with XP SP2.
I also have a Zen Micro 6 GB that works perfectly.
Recently I attached the Zen to the laptop and every time I receive this message:
"PowerSurgeOn Hub Port. A USB device has exceeded the power limits of its hub port."
I take the Zen to my work computer and it works perfectly.
?What is the problem?
Thanks,
Regards,
Lorenzo

^your laptop is unable to provide enough power to charge your Zen Micro.
If it has other USB ports, try using them.
It may be a case that the laptop is not designed to power external devices like the Zen Micro.

Power Surge UMTS KPN dongel T430 with Windows XP

I have Windows XP SP3 installed on a Lenovo T430, now I get the message: Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port.
On Windows 7 the UMTS dongel works good.
How can I use Windows XP with servicepack 3 and the KPN UMTS dongel?

Hi,
Welcome to Lenovo Community Forums!
I’m sorry to hear that you are getting a message “Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port” in your Lenovo ThinkPad T430.
I would suggest you to go to Control panel -> Device manager -> uninstall all the devices under Universal serial bus controllers, then restart the computer to let XP install all the USB ports again. Later, find the chipset and USB drivers from Lenovo support page and install them.
Hope this helps!
Best regards,
Mithun.
