Power surge on hub port

I keep on getting a tab that says there is a "power surge on hub port" and it is causing my computer to run slowly. the message reads "a usb device has exceeded the power limits of its hub port. forassistence with this problem click this message".... then when i click the message it reads "the usb device has malfunctioned and exceeds the power limits of its ub port. you should disconnect the device." i don't know which hub it is referring to/ or it's location (it is the fourth one on the list), since there are only two hubs being used total. one hub, the sixth on the list is for a wireless g 'usb adapter, and the one that is in bold is the fourth one and is called "and unknown usb device". can't get the message to disappear.

Try this to find out which one of your components has an issue. Turn off your machine then unplug all of your USB cables. Turn your machine back on and plug in one of your USB cables. Verify the component you just plugged in works correctly and if it does plug in another cable and verify that component is working. Continue these steps until you have the one component that displays the error you have seen. That component is most likely the cause of your issue and should be replaced.

Good luck, Greased.

I have sahara n1356 laptop which freezes mouse and keyboard when i start it. what could be a problem


Try following tips:
Try to connect your keyboard and mouse directly to your laptop's USB ports (instead of using the USB hub) and see if they still freeze.
OR
It sounds like you're using an unpowered hub, which in my experience tends to cause most common errors with USB peripherals. It's definitely not recommended to connect any USB devices which aren't supplied with a power adapter (for instance some 2.5" external HDs and those small photo printers). These sort of devices should be connected directly to your laptop at all times.
You could also consider buying a powered hub, i.e. an USB hub which draws its power from a separate power adapter (and not your single laptop USB port).

if it doesn't work you can try this..

Click Start, and type device manager in the Start Search box.
Click Device Manager in the Programs list.
If you are prompted for an administrator password or confirmation, type your password or click Continue.
In the Device Manager dialog box, expand Universal Serial Bus controllers.
Right-click USB Root Hub and then click Properties.
In the USB Root Hub Properties dialog box, click the Power Management tab.
Remove the check from the Allow the computer to turn off this device to save power check box. Repeat steps 1 through 4 for each USB Root Hub listed in the Device Manager.

Under Power settings, check the 'USB settings' -> 'USB selective suspend settings' and make sure it is disabled.
Check Thumbnail, highlighted: Open Device manager, Double click on Universal Serial Bus controller at the bottom, Double Click USB Root Hub, Click Power Management on top right, Uncheck Allow Power...
Hope it works for you.

It is referring to the USB ports on the back of your computer near where your keyboard plugs in. The front ones must be USB 1.1 which will cause this error.

Usb port not recognized any device


  • Don't worry just follow the simple steps and get rid out of that problem
    • Unsecure or Loose Connection
    Unplug the presently connected USB device (if any). It is quite possible that the connection is not secure and has become loose. Re-plug the USB device tightly and firmly into the USB port. This is one of the most common reasons for an error in detecting a USB device.
  • Scan for Hardware Changes in Device Manager
    Use the Device Manager to scan for new and recently installed hardware. From the Start menu, select the Run option. In the pop up box, type in Devmgmt.msc and then click Ok. From the Action menu, click Scan for hardware changes. This will make Windows scan & recognize any new devices that are installed. Now, close all opened device managers and control panels. Now, follow the above step and see if your computer detects the USB device.
  • USB Hub Power Management
    Disable power management of the USB hub. To disable the power management on the USB hub, follow these steps; Click Start, and then click Run. Type devmgmt.msc in the popup box, and then click Ok. Expand the Universal Serial Bus Controllers' node, and then follow these steps for each USB Root Hub that is listed.

    1. Right-click the USB Root Hub and then click Properties.
    2. Click the Power Management tab.
    3. Click to clear the Allow the computer to turn off this device to save power check box, and then click Ok.
    Note: If you perform the following procedure on a laptop computer, you may reduce the battery life.
  • Sometimes, simply unplugging the USB device and turning off the computer for twenty minutes and then restarting may solve the issue. If none of the above options have solved the problem, check the manufacturer's website for new driver information. It is possible that your drivers need to be updated. There could also be a possibility of hardware failure, which needs to be checked by a hardware expert.
Please rate me if this solution works for you

Thanks......Have a great time

Anytime I plug something in to the USB port it give a error message that states, Power Surge on the USB port. What can I do to fix this?


The USB device could be drawing more current than the USB port can supply or the USB port may be faulty.
Get a powered USB hub and plug it into your computer's USB port and then plug the USB devices into the powered USB hub.

I can't get my Compac Evo N610 to reconize my docking station usb ports what do i do?


I have a solutions that might work, please for the love of god, next time give it as much detail as possible. Navigate to Start>run type:MSCONFIG. Enable everything unless you are absolutely sure you don't need it.
Right click on My Computer, click on properties. Go to the hardware tab at the top, click on device manager to see if there is a conflict.
Try a different port.
Try the hub on a different computer.
If your hub has a power input, now would be the best time to plug it in.
Plug directly into computer.
Make sure the device is plugged in securely, same goes for the devices plugged into it.
If that port is for power only and you plugged it in thinking it would work for data, please don't ask.
Any error messages?
If your computer can boot off a flash drive, Go to bios, test the port and the hub.

Power surge on hub port on my computer


Try unplugging everything from the hub and if that doesn't work then disable the hub.
You can either buy a new hub or buy a USB card. Both get the same results.

I plugged my Memorex TravelDrive into my computer. It has always worked perfectly. This time I got the message that the USB device was not recognized and I can't get into my files.


THE FOLLOWING IS COURTESY OF MICROSOFT Help and Support

When you plug a USB device into a Windows XP-based computer immediately after the computer comes out of standby (S3) or hibernate (S4), the computer may not recognize the USB device. When this issue occurs, the USB device may be listed in Device Manager as an unknown device, and you may receive the following warning message:
Unrecognized device has been found.

This issue occurs because, when the computer comes out of S3 or S4, there is a five- to ten-second period when the selective suspend feature of the USB driver will interfere with detection of a new USB device connection. The time period depends on several factors. This includes the following factors:• Host controller hardware
• Attached hubs
• Attached devices
• USB driver versions
• Support for USB 2.0
• Additional system hardware or configurations that may change the timing
There may be other reasons that a USB device is not detected

Method 1
loadTOCNode(2, 'workaround'); After the computer comes out of S3 or S4, wait five to ten seconds before you plug the USB device into the computer or hub.

Method 2
After the computer comes out of S3 or S4, unplug the USB device, and then plug the device back into the computer or hub.

Method 3
Use the Device Manager to scan for new hardware. Follow these steps: 1. Click Start, click Run, type Devmgmt.msc, and then click OK..
2. On the Action menu, click Scan for hardware changes. This causes Windows to recognize new devices.
3. Close Device Manager and Control Panel.

Method 4
Disable power management of the USB hub.
Note If you perform the following procedure, you may also reduce the battery life on a portable computer.
To disable power management on the USB hub, follow these steps: 1. Click Start, click Run, type devmgmt.msc, and then click OK.
2. Expand the Universal Serial Bus controllers node, and then follow these steps for each USB Root Hub that is listed: a. Right-click the USB Root Hub, and then click Properties.
