usb device has exceeded the power limits of its hub port"

[GoingUp]

Just got a USB 2.0 kit and installed the HD. I get this damn error everytime I try to plug it in to my computer. The damned external case is powered. I tried it on my ABIT NF7 and my Dell 8600. Both are running winXP pro w/ SP2.

Any suggestions on what to do?

You didn't elaborate. Is this happening on both computers or only one?

If it's happening on both then I would suspect there's a problem with the external drive enclosure. It may be drawing power from the USB bus even though it shouldn't.

If it only happens on the one computer, then maybe the USB 2.0 card you bought is defective.

Are you pluging straight into the USB port or are you going through a hub? You should always try to connect a HDD direct to the port.

What brand\model USB case kit is it?

The USB bus can only deliver 500mA (+5V).
Some lower quality kits use VIA, PC Chips, & ALi chipsets which
are probmatic with low power levels.

A powered hub would eliminate the problem but should not be required.

all of my hubs are powered. The hard drive is powered. I have turned off all warning messages and it still doesnt work!


ive disabled all error messages and it doesnt work. it doesnt work when I plug it into my mobo or a hub.

edit: I have the koutech USB case that was in hot deals a couple of days ago. its model# is eeu325

i powered off my hub then turned it back on and it temporarily worked. then it failed in the middle of the format of one of the partitions. now im getting the same damn surge errors.... very frustrating.

WORKAROUND
To work around this issue, you must power the USB device by an external power source if one is available for the device. For example, you may be able to use an AC adapter to power the USB device.

Did you read this carefully? I don't see how this applies to your situation. The problem MS is describing is only with devices that are not powered.

I don't think installing SP1 will help. All it will do is supress the error message, but you may still be drawing too much current from the USB port is the USB enclosure is defective.
