Usb port power surge and has failed to work. How do I reset it in the (dialog??) box???

INSUFFICIENT POWER - USB PORT
If you get an error message "Insufficient power to operate USB device" when you plug a USB device into the computer's USB port or the un-powered USB hub that is attached to the computer's USB port, then this device is drawing excessive current that the USB port cannot supply. The maximum output from an USB port is 500mA. In case such as this, you need to purchased a powered USB hub and connect this hub into the computer's USB port and then connect the USB device into this powered USB hub.

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.

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.

There may be problem with the usb ports.

To turn off this error message, follow these steps:

1. Open Device Manager. To do this, click Start, click Run, type devmgmt.msc in the Run window, and then click OK.
2. Expand the Universal Serial Bus Controllers section at the bottom of the device manager window. Locate and then double-click a host controller that has either the word Universal or the word Open in the title.
3. In the properties dialog box, click the Advanced tab, and then select the Don't tell me about USB errors check box.

I had a similar problem with Vista Home 32. Finally tried an old external USB 1.1 hub that I had laying around and now everything works all the time in FSX and X-Plane. It is rock solid. Can't make it fail even when I try. I also tried a USB 2.0 hub but had the same problem with that. I can't say for sure it will fix your problem but it is worth a try.

Some USB devices draw excessive power from the USB port, especially USB scanners. When this happens you need a powered USB hub, connect this to your computer's USB port and connect the USB device into the powered USB hub, you should not have any further error power surge problems.

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..

Electrical surge on hub port. Either a device attached to the port, or the port itself, has drawn more current than allowed, and the hub turned off the port. The port will not function correctly until you reset it. If the device is the cause, it must be detached before resetting the port. To reset the port, disconnect the device, and then click Reset in the dialog box. If the port is the cause, close the dialog box, and do the following to re-enable the port:
Disconnect the hub.
Re-attach the hub.
If it is the root hub, unplug all attached USB devices from the computer, and (if they have power supplies) unplug them from the electric supply. After a few moments, reconnect the devices. The computer can be restarted at any time.-->

You might have too much power in use from the USB ports on your machine: Try unplugging some USB devices you do not need, and trying again.

I have this issue with several devices I own: not really with my zune, but I never charge it with the PC: I use the AC power adapter, which I STRONGLY recommend any zune owner purchasing.

Hello mandag78,

The error message you are talking about occurs when a device tries to draw more power from the USB port then the port can provide,

Make sure you are connecting the MP3 player directly to a USB port on the computer or a USB hub that has an independent power source (one that you plug into an electrical outlet). If you are plugging your MP3 player into a USB keyboard or a non-powered hub the port may not have enough ower to charge it.

I am assuming tha tthe Zen was working before? And that you are sing the exact same USB port and cord that you were using to charge the item previously? If so, then what you are experiencing might be a sign that the unit has failed and is in need of repair.

Best Regards,
Ken

The printer is the problem, obviously but, also try using a different USB cable to see if that doesn't help! When plugging up th cable, look for anything out of the ordinary! If changing the USB cable doesn't resolve the situation then it could be something shorted out in your printer and you need to take it to a service shop for repair! regards, babb
