USB Port Stopped Working after Power Surge

Q: USB Port Stopped Working after Power Surge

Hi

After a power surge on hub port when attaching a card reader to a front USB port one of my external hard drives disappeared.

The drive works fine and is now on another USB port.

The non functioning rear USB port has the following properties (image 1) and the location address looks weird compared to the functioning USB port below it (image 2):

I have tried uninstalling/reinstalling the driver and disabling/enabling, rebooting etc and it still will not work.

Any suggestions are welcome.

Thanks

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

How do you know there was a power surge at this time?

I am not sure your first screen shot is of the port, I note it says device. But I agree, the location looks bad.

Have you totally shut "off" your computer? Not just reboot, or "shutdown", but totally off by unplugging from the wall (or setting the master power switch on the back of your PSU - IF it has the option - to off). This is the only way to totally remove all voltages, in particular the ATX Form Factor required +5Vsb standby voltage PC power supplies supply when the computer is simply shutdown (which is really standby mode).

Note there are several "Wake on..." commands set in the BIOS Setup Menu that use this +5Vsb voltage to keep various circuits and settings "alive" when the computer is in standby mode. These include Wake on Mouse and Wake on Keyboard - which obviously rely on USB. That means USB ports are still alive even when you have exited Windows and shutdown the computer.

If me, I would uninstall your device and the drivers, shutdown, then remove power from the computer for 10 - 15 seconds to ensure all standby settings are released. Then connect and boot and see if the device is detected, drivers load, and it works.

I am assuming you have inspected the interior to ensure the necessary wires from the front panel USB ports are securely connected to the motherboard.

That said, if by "power surge" you mean the USB connector for the card reader was not perfectly aligned when you tried to connect it and you "shorted" the +5V that was present in the computer's USB port to another contact (possibly seeing or hearing the "zap"), then the controller for that pair of ports may now be bad.

A:Power surge/usb port not working

The error usually means a USB device is drawing too much power. It may or may not have already caused USB power damage. If the issue only arises when using a particular device, then that device is likely the cause and/or faulty. If it now occurs with all devices, I'd suspect the USB controller is damaged/faulty.

After a power surge, a Gateway DX4200-09 with an upgraded processor stopped working. Due to limited funds, i bought a Used power supply and replaced it. I also bought a refurbished motherboard stock for the computer, and put it in. The computer turns on , fans on the motherboard spin, but the monitor displays nothing. The power supply fan is NOT spinning. Is this an indicator that the Power supply is bad? Power on the motherboard panel ( USB ports and etc., ) the components will "flicker" and then not work period, unless i tamper with the wire , unplug it replug it in. then it will flicker again. CDROM pulls in and out. Wiring all done correctly. Could this also be a processor problem? I am so aggravated

I'm having a bizarre issue where simply unplugging the official Lenovo power supply from the orange USB power port causes the laptop to immediately issue the subject warning, along with the detail "A USB device has malfunctioned and exceeded the power limits of its hub port".   This warning pops up every 5 seconds, unless clicked on, where reset/close options do nothing.  Crazy thing is, NOTHING is plugged into any USB port!   Reattaching the power supply does not clear the error.  Only rebooting with the power supply cable connected clears the error.   Remove the power cable, and the error instantly comes back.   All of the USB ports actually work fine, including the USB C port, whether or not this message is active. Maybe it is a hardware issue, but ALL the USB ports actually work fine.  I can't figure how unpluging the power source can trigger a USB power surge when nothing is actually connected and the battery is fully charged.  I've removed/reinstalled the USB Root hub, eXtensible Host Controller, Generic USB Hub, etc., drivers multiple times to no avail.   No errors with any devices are apparent in the device manager. I've seen a lot of issues reported about USB power surges but none like mine.   Anyone have any ideas about this?  System: Lenovo Yoga 900/16GB/Windows 10

@mee_anders I have the same problem and I'm extremely disappointed in HP's lack of support. I've tried and tried to convince them to take responsibility for this issue but they won't. I'm guessing you saw the thread "HP - Spectre x360 power problem" - I'm actually wondering if some of us who were told we need to replace our motherboard actually have a defect part that you mentioned.

The power port on my Spectre laptop (Product No: K6C18AV) just stopped working. The power cord is plugged in but it is not supplying power to the laptop and is not charging the battery. The small LED next to the power port is dead, no amber or white color. I've tried a different power adapter and different outlets in my house. After doing some reading on these forums, it seems others have had a similar problem. I bought the laptop in April 2015. Warranty expired April 2016. I called HP support. They said the motherboard needs to be replaced. Minimum charge $600. Fudge, I might as well buy a new laptop.   So Questions:-Has anyone had luck replacing the DC power port inside the laptop? I found a part number PN 801513-001 on one of the forums. -Has anyone had any luck convincing HP this is a common problem and should be covered as a defect even though the laptop is out of warranty?

I have never had this problem when I connect my Samsung MP3 player. Now I receive this message:

When I click on the message, I am prompted this:

Hello People!

For a number of months now I've been getting this failure:-


Quote:




Power surge on hub port

a USB device has exceeded the power limits of its hub port.
For assistance in solving this problem, click this message




Background first, a couple of years ago, for whatever reason, my onboard USB Ports [x2] just stopped working. The kind people on this Forum tried and tried to help but it just wasn't to be. I therefore purchased a 5 port PCI USB Card [not externally powered] and placed it in one of the available slots inside my PC. For a few weeks it worked fine but now only 1 port seems to work properly. I can ONLY have 1 device connected to the hub at any given time, if I put my printer or MP3 player in while my broadband Modem is connected I get the above fail straightaway. If I was to leave my Internet connected for a number of hours I will eventually get the above fail, the Modem lights would go off and I'd have to turn the PC off fully each time which is so annoying and frustrating! I have read about the self-powering hubs and was just wondering - is this what I need or is my Motherboard simply not good enough for the job? It's a Jetway Socket 360 MoBo I bought in 2001.

Any help on this matter would be great, I don't really want to purchase a powered Hub to find out my PC can't handle it.

Thanks a lot
Gerard

Well I just got a brand new medion computer (4GB ram, 1GB nvidia graphics card, dual core i5 3.0Ghz processor, etc) about 3-4 weeks ago and have had no problems till now. The problem is when i bought the computer i got a mouse and keyboard which worked with it till about 2 days ago. I have 3 USB 2.0 and 3 USB 3.0 slots and. 2 of each type are on the back and the remaining 1 of each are on the front. Now, anytime i plug both the mouse and the keyboard into the back i get a warning message at the bottom right saying "USB hub port power surge" or something along those lines and neither device works. But if i un-plug them both and plug back in the keyboard, the keyboard works. I have tried restarting my computer. I have even tried turning the computer off, un-plugging it from the wall. Than holding the power button so it quickly flashes on and than off again (I hear this resets usb ports Link: Reset of USB port after probable power surge ) I than plug the computer back in and start it up but still neither devices work unless i unplug the mouse. I have also tried plugging in memory sticks and other devices and they work until i plug the mouse in beside them. Every now and than they un-expectedly decide to work together and than stop as randomly as it began. Any help or advice would greatly be appreciated

Hi when I plug in my Razr V3 cell phone to my pc, I get the "Power Surge on Hub port" message and the USB ports shut down till I unplug the phone. However, I was able to bypass this error and get my USB phone to work when a computer guru let me borrow this special USB cable that had one end that connected to the phone, but the other end had 2 USB plugs that simultaneously connected to 2 of my USB ports instead of one. I was told that this way, the power supply demands of my phone were split and shared betwen the 2 port. Now I'm trying to buy one of these special USB cables but I don't know what it's called. Would really appreciate your help.

I am suddenly having trouble with my printer/scanner. When I try to use it, a message pops up saying "power surge on hub port"; when I click on it I get instructions to disconnect the device and press reset. I do this but the same thing happens when I plug the USB cable back in. I cannot use my printer and urgently, urgently need to!

I'm running WinXP Home edition with latest service pack installed. I've got a Dell emachine 4250, intel celeron D, 80GB PATA hard drive. The printer/scanner is an Epson DX7400. Connected via USB cable supplied with the printer directly to the USB port on the back of the computer. I have tried connecting the USB to all the other ports on the computer with no luck. The printer is only a few months old and was working perfectly until now. I have read whilst googling this problem something about issues with service packs and there possibly being a fix/patch?

Any help is hugely appreciated as I so desperately need to print today!

A:Please help! Power Surge on Hub Port

I have seen this on a couple of machines and if it is coming up when you have nothing plugged in to the USB then you probably have hardware fault on the USB ports. Could be a Mother board or Add on card depending on your type of machine. So if its under warranty get it fixed.

If it is happening only when you plug in the printer then the power being drawn by the device may be causing the problem. You could invest in a externally powered USB hub and try that I recently purchased one for $19 Aussie Dollars.

However I did read this post from another emachine owner so read on.

**************************************************

Hi happyrck, Well I found the fix at E-Machines web site online chat with a tech. What he said to do is," delete all the USB ports in the devices manager, then restart the computer to let XP install all the USB ports again. Then he said to go to the first USB port and right click on it and go to properties. Then on the advance tab click on do not show warnings".
It worked!

I wonder if anyone can help.

I have a HP Compaq NX5000 laptop that runs without a fault apart from 1 annoying problem.

I have a 2.5" external HDD with a 60gig HDD installed. Every time I plug it in to the usb port I get the small popup error stating "Power Surge On Hub Port".

Now at first I thought it must just be my HDD pulling to much power but I can plug this into other laptops in the company and never have the problem. Can you suggest any reason for this and any way to rectify it.
Thanks

A:Power surge on hub port

It may still be the HD drawing too much power. Most 2.5" hard disks ship with a two-headed USB cable to draw power from two USB ports, because the startup power exceeds the limits for one USB connection. I have several 2.5" USB drives, and with some systems, you can just use a single USB connector, others require both to get enough power to run the laptop.

My system, see specs for details, started to popup this error message:

"The usb device exceeded the power limit of its hub port"

Clicking on the message brings up this window:



There are two USB devices plugged in to the computer, keyboard and mouse in the USB 2.0 ports, when the message pops up. The same keyboard and mouse had been used for years without any issues. The Dell keyboard does have two USB ports, but they are not used.

There's nothing to disconnect and selecting the option of "Reset" in the above image does not fix the issue. The keyboard and mouse does work just fine during the reset. While the eSATA should have no relation to this issue, disconnecting the eSATA external drive did not fixed the issue either.

Since the issue does not relate to and actual device, it seems that the motherboard's power delivery (capacitors?) could be the reason for the error message. Is there a way to check this power delivery?
TIA...

I would check first with another keyboard and mouse. One of the present ones may have started drawing more power than normal. Quite possible.

Looks like something is bad then.. Maybe the USB controller or the wiring for the front panel USB connections.

Are you sure you have no actual USB devices? Things like memory card readers are somethimes wired to USB inside the computer.

What's that all about?

'A USB device has exceed the power limits of it's hub port, for assistance in solving this problem, click this message'

Then it pops up a little menu showing a few USB ports (one being used by my Dell Wireless internet adaptor thingy). The one causing the problem is "unkown device" in bold, it's whenever I plug in my webcam, so that is obviously the problem

Trouble is, it keeps happening, my webcam used to work fine, I've been using it for ages and ages, when I plug in my USB connector to my Pocket PC that works fine.. but now that my webcam doesn't I'm quite confused...

If anybody could help me I'd love them forever... please please.

If you need any more information just ask Thanksyou in advance! Mike!

Whenever I plug in my iPod to the computer I get a message that reads:

"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.

USB Root Hub (8 ports)
Unused Port
Unused Port...
?UNKNOWN USB DEVICE
?UNKNOWN USB DEVICE
Unused Port
Unused Port

Recommendation: To Re-enable the port, disconnect the hardware and click Reset. If you click Close, the port will no longer function."

I've tried plugging in my ipod connector into the 6 USB ports in the back of my computer but it doesn't fit. The only other thing I have plugged in is a mouse- that's been plugged in for years and I've had my iPod for a year and a half and it just randomly started doing this.
Please help me!

I have a Toshiba Satellite Pro laptop 3.2 Ghz, 512 RAM. I reloaded XP SP2 because various problems were occurring such as

"svchost.exe application error. the instruction at "0x745f2780" referenced memory at "0x00000000". The memory could not be read. OK to terminate program, cancel to debug." OK terminating usually disables running standard programs requiring reboot, cancel usually not so.

And the Realtek Audio device uninstalling itself every restart.

These problems have now gone but some remain which I'd like info, help, advice on;

1. Plugging in various USB devices that have worked fine on other systems and on this one some months ago (CD/storage drives etc) gives

"Power Surge on Hub Port.
The USB Mass storage device has exceeded the power limits of its hub port"

It allows you to reset the port which sometimes enables the device to be active for some minutes, but often half way through moving data around etc. shows again. It also depends on the port as to how long it will last if at all, and the laptop and device does heat up reasonably.

2. Before reloading XP many blank media recorded or not, and other data CD's & DVDs would not read in the DVD RAM drive, and often I'd get "D:\ not accessible/valid" or something, and DVD/CD Recording was often unsuccessful even when blank media was recognised. This doesnt seem to be happening after a reload and clean, but sometimes still blank recorded media is... Read more

Good Morning diddykong, it would appear that you have more than one problem which possibly has a common cause.
You might try obtaining this Everest program..
http://www.majorgeeks.com/download4181.html
Load it and navigate to the computer applet, then sensors, this page gives temp and voltage readings internally in the machine. (if the sensors are in the system)
If you do this and there are readings there, you might copy and paste that page back here in your next post.

qldit.

Hello.

I received a new Olympus camera for by birthday. I attempted to plug it into my fujitsu lifebook USB port to retrieve the pictures I had taken when I got an error message stating that my device exceeded the power supply. Now none of my usb ports work. I have nothing plugged into them now or when I plugged the camera into the port. Is there an internal surge protector of USB ports that I can reset? I have checked the device manager and it states that all the ports are working but they are not putting out any power. I tired downloading the drivers but that did not work.

Please help.

thanks,
S

Hi All,  I purchased the T460 for my wife during the Thanksgiving, and we just got it for two days. Today is the first time that we opened the package and started to use it since we have been busy. At first it looks ok, but just a few minutes, it starts to pop up the error message "Power surge on USB port". And the funny thing is , I don't have anything plugged in the USB port. It is windows 10.  I have screen captures:  I clicked the message on the right bottom, it pops out another message window: I tried all the solutions online and on this forum to solve it, but they all failed.So I am desperate now, and I am not sure if some part of the labtop is defective, in which case, I have to contact the customer service for return or exchange.  before going to that, I hope you guys can help with this problem.  Thanks!

I just did a reinstall of my friends E-Machine and when I try to install the printer (hp PSC 2410 xi photosmart all in one) I get this message when I go to plug in the USB cable to the computer from the printer. In the task bar I get this message: "Power surge on hub port. A USB device has exceeded the power limits of its hub port".

I also have installed an creative sound card too, but I can't see how that could be a problem.

I've never ran into anything like this before. Any ideas?
Thanks
