A USB device has exceeded the power limits of its hub port

Ewwwwwww... no fun.

You should try a "POWERED"

4 Port USB 3.0 Hub It's important that it's a "POWERED HUB" because you need the HUB to supply it's OWN power and not depend on your Apple E to provide power to your connected USB devices!

The good news is they don't cost much: $8 on eBay
Auction: 202096902632
Note that they include the power supply! Many other HUBS don't.

Your HUB is even LESS if you pick on the USB 2.0. Version, AND YES, each HUB MUST have it's own power supply and that's just what YOU need.

The ONE thing I didn't like about this HUB is the LED lights that are provided for each port! They are TOO bright so I opened it up and plucked all but one LED out. I also bought the 8 and 10 Port HUB versions and 'fixed' them too.

I also didn't need the switches to confuse things (accidentally turn one or more ports OFF)... so my trusty hot glue gun fixed that! All are constant ON now.

If you get an error message"Insufficient power to operate USB device" when you plug a USB deviceinto the computer's USB port, then this device is drawing excessive currentthat the USB port cannot supply. In case such as this, youneed to purchased a powered USB hub and connect this hub into the computer'sUSB port and then connect the USB device into this powered USB hub.

Problem :Overvoltage on USB hub port
Solution: Look carefully at that same port and you will four gold pins make sure they are NOT touching each other..

Some USB devices draw too much current from the computer's USB port and you get an exceed power error message.
To get around this problem, get a powered USB hub and connect it to the Computer's USB port and then connect the troublesome USB device into the powered USB hub.

Hey,

Let me know if you need anything else.

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.

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.

If your using a USB hub, unplug another device (i.e printer or scanner, fax, etc.). Plug in your One Touch. Then turn off your pc and turn it back on. This should work.
If you use a alot of USB devices, you may need to get a USB Power Hub.
You can try an plug in the One Touch straight to the pc and unpluging all other usb device except the keyboard and mouse.
Let me know if this helps. You also may need to move the ac power to another outlet.

Hello,

Hi there. This message would indicate any one of the following: 1. You have a lot of USB devices plugged in to your computer, and the maximum power supply for the USB ports has been exceeded by plugging this player to your computer. It would be best if you unplugged 1 or 2 of the USB devices connected for the time being. 2. You are plugging the player on your front USB port, and may need to plug it in the rear USB port to acquire ample power supply (front USB ports do not get as much power as the rear USB port -- sad but true) 3. You are using a laptop and may need to try another USB port on that computer. Purchasing a self-powered USB hub would be ideal as it gets its power supply directly from the wall electrical socket.
