Error message usb ports force stopped because of too much power


It will still be covered by the warranty, take it to an apple repair centre, they will have Apple hardware diagnostics software that will be able to determine the cause of the fault. Worst case scenario will be they have to replace the logic board.

If you are using some sort of USB hub the number of devices you are connecting to that single port may be drawing too much power. Try to determine how much power each device is drawing then ask at an apple store how much power the USB port can supply.

Is it ok to keep my usb hub plugged in to my macbook all the time?


Yes, you can leave the USB hub connected without issues for your MacBook. Just keep in mind that some of the devices you plug in to the hub will draw power from the Mac; if you're running on battery power, this will lessen your time between needing charges.

It may very well be drawing too much power from your laptop. These are fairly intolerant of devices that draw higher current like printers and some hard drives. You may need to get a small USB Self-powered hub. These are USB hub/splitters that have their own power supplies. These usually provide and tolerate higher power draw. To test, if you can connect the same printer to a desktop, you will likely see it works fine.

Symptom: When scanning you receive an error 250. Cause: This problem can be caused by several different things but is often a driver or communication problem. Solution: Here are several solutions that can resolve this problem:

Solution 1 - Check for communication problems

Using any of the following can cause communication errors:
  • USB hubs
  • Docking stations
  • USB extension cables
  • USB cables longer than 6'
  • Connecting the scanner to one of the computers front USB ports (desktop computer only)
Connect the scanner directly to a USB port on the back of the computer (or side for notebook computers) using a 6 foot or shorter cable.

If you still receive the same error message, try a different USB cable.

Solution 2 - Redetect the scanner with Hidden Devices

Windows Vista, XP and 2000 users
  1. Disconnect the power and USB cable from the scanner.
  2. Click here and select "Run" or "Open".
  3. The Windows Device Manager will open.
    • Click on the "View" menu then select "Show hidden devices".
  4. Click the "+" next to "Imaging Devices". This will show all Imaging Devices previously and currently connected to the computer.
  5. Right-click on the Visioneer or Xerox scanner name and left click on "Uninstall".
  6. If the scanner is listed more than one time, uninstall ALL occurrences of the scanner.

If possible, you should try the scanner on a different computer. If the scanner works correctly on a different computer, then the problem is environmental and may be related to your chipset. See solution 6 below.

Solution 6 - Check the computer's chipset

This problem can also be caused by the computer's chipset. To check the chipset:

  1. Vista, XP and 2000 users: Click here and select "Run" or "Open".
    ME and 98 users: Right click on 'My Computer', select 'Properties' then click the 'Device Manager' tab.

    • ALi
  6. If your chipset is one of those listed above or it is only listed as 'Standard', you can try updating the chipset drivers.
    • Contact your computer's manufacturer for more information.
  7. If the problem persists, you may need to use a USB add-in card.
    • This is a PCI card that will add more USB ports to your computer.
  8. For more information about USB chipset issues, see www.usbman.com.

My computer says the USB port connected to my mp3 is drawing too much power and has shut down the USB port. How do I get around this? I have a MacBook Pro.


It look that your player is drawing too much current from your Macbook Pro: it is rather unusual nowadays but does happen even with some USB external 2.5in drives!
Solutions:
1) Buy a USB Power Adapter Y cable that plugs into 2 usb ports on your Computer an thus allows double the current (shop around as they are expensive on Amazon but pretty cheap on Ebay)
2) Plug your player via a 'Powered' USB Hub that can provide higher current (from its 'own AC/DC power pack') to each USB port on the Hub

Hioe it helps!

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.

Western Digital Passport 160 GB external HD won't load.


WinXP SP2 blocks the use of the drive because it thinks it draws too much power. But there is a simple procedure to override this (from WD site):

"Problem:
Under Windows XP, an error message of "Power Surge on Hub Port" or "USB device has exceeded the power limits of it's hub port" is displayed when connecting a USB device to a USB port on a computer or Hub.

Cause:
Under some computers, USB devices are only allowed to draw a maximum of 500 milliamps (mA) per connection from the USB port on the computer system or from a USB hub. Under the Windows XP Operating System, with the release of Service Pack 2, if a device attempts to draw more than this (500 milliamps), a USB port balloon message is displayed to indicate this over current condition. When connecting a USB device that draws power from the USB bus, a very brief over current condition is sometimes detected by the OS, and the warning message is displayed.

Resolution:
This message has no affect on the functionality of the USB port. The USB hard drive should still function correctly on the USB port regardless of the error message. To prevent the USB Power Surge Alert message from displaying, please complete the following steps:
Click on Start.

Click on Control Panel.

Double-click on the System Icon.

Click on the Hardware Tab.

Click on the Device Manager button.

Click on the + next to Universal Serial Bus Controllers to expand the selection.

Right-click and select Properties on any listing that displays USB UNIVERSAL HOST CONTROLLER.

Click on the Advanced Tab.

Check the box that says: Don't tell me about USB errors."

This works fine, and the drive works fine afterwards. I suspect it actually draws less power than they say. Maybe it has a brief power draw spike on startup, but it's running power seems less. In any case, it works fine without the Y cable. I do think it is tacky that WD doesn't give the cable for free, since my $7 Sabrent 2.5" Hard drive enclosure came with a y cable.

But most likely the drive will work fine for you. It is a lovely quiet drive, and takes up no space at all.

Service Plan repair (#C3978905) on laptop


This problem could occur if one or more USB devices are drawing more power than the USB port can deliver.
You can purchase a powered USB 4 port hub and connect it to the laptop, this would supply independent power and not draw power from the laptop.
