USB power exceeding error

August 20, 2009 at 05:20:05
Specs: Windows XP
I have HP D330 Motherboard and 2.4 Ghz intel processor.
I have about 4 usb ports at the back(all of which are working completely fine)
and 2 at the front(both of which give me the exact same error that usb power has exceeded) and this usb port has blown out nearly 2 flash disks(usbs)

So everytime i plug in any usb keyboard or flashdisk, these two usb ports give me this particular error!

Help me out please

definitely am gonna use the front ports as they are always easily accessible .

Temme whats the actual problem ? Is there some problem with the ports or the wires ?
Secondly, what things should I look for in the market to replace these usb ports!

If the ports are built into the case you will need to get them from the case manufacturer, they are soldered to a PCB.

No .. i dun have a reader

Actually i had Intel's motherboard D84865GBF before which i replaced a few days back with this HP D330

Now. . this is the problem that im facing! not being able to use the front two usb ports!
Whats the main problem anyway :S or the cause :S

You may have connected the front ports to a 1394 fire wire header. They look the same. Or, you may have the wiring connected wrong. Nothing will happen if connected wrong or to the wrong header UNTIL you plug in a USB device.

Look at the manual for the board and it will show you what header are for what. You might not have the wiring connected to the wrong header. I was throwing stuff out there that has happened in the past.

Additionally, Gigabyte motherboards use a different pinout on the external USB header. While you don't appear to have a Gigabyte board I mentioned it because I have also seen cases with Gigabyte type connectors that would give the same results.

The odd thing about what you describe is that in my experience with this issue what has happened is the USB controller was blown. Didn't appear to damage the USB port. Did damage a USB hardware lock that I am aware of.

The point is that something isn't wired right. A wild guess would be a stray standoff right under that USB header that is shorting it out only when you plug in a device.

You got what from a friend? A complete tower or just the motherboard?

Post the model of the board and we can provide a link to the manual.

If you don't KNOW the model number then download SIW and use it to learn most everything about your system. Get SIW at the link below.

HP motherboard is not the model of the board. HP doesn't make motherboards.

If that is the model of the computer then post the COMPLETE model of the computer.

This is what my friend told me that Hp D330 is the model of the motherboard!

However the software that u asked me to use displays Model Number : 085Ch

The HP D330 is HP's designation for the Intel 085Ch motherboard.

I couldn't find a complete manual but I did determine there is no 1394 Firewire available on that board. Therefore you couldn't have connected USB ports to a 1394 header.

The only mistake you could make is what I described above about the pinouts on the USB being wired wrong.

Do you have a single multiple wire connector for the front ports or TWO connectors or individual wire connectors?

Hunted more and came to the conclusion there were multiple boards used in the D330. That is the computer model by the way as well as the designation of the board by HP/Compaq.

So, there might still be a 1394 header on there. I am linking diagrams of USB header pinouts.

HP and most other brand name builders did not make the mboards that are in their systems - they are supplied to them by major mboard manufacturers. It can often be determined which mboard manufacturer actually made the desktop mboards and what models they are.

Sometimes the wires to front ports are inadequate and those ports won't work properly with some USB devices.
However, if the same front ports worked fine with your previous mboard, there is probably NOTHING WRONG with the USB ports or their wires.

"... i already destroyed ma two usbs by plugging them into these two front ports* "

As OtheHill has pointed out, some mboards (e.g. Asus, some Gigabyte) that have both USB and firewire (1394) have identical placement and numbers of the pins on the USB and firewire headers.Sometimes they are beside each other on the mboard. They often have different colored plastic below the pins.
If you connect USB wiring to a firewire header, or visa versa, you won't notice anything wrong when there is nothing plugged into the mis-wired ports,
but when you DO plug something into the mis-wired port, all hexx breaks loose!
You may or may not get an error message, but in any case the device you have plugged in, and possibly the circuits connected to that port, will be damaged in a very short time!
This is probably your problem!

HP D330 is simply too vague.
That can apply to any of these MANY HP models:

"HP D330 is the motherboard that i got from my friend!"

If your friend still has the brand name case the mboard was in, ask him to find the specific model number - it's on a label on the outside of the case somewhere - then use that on the site I linked to above to look up it's parts - PC Board is what they call a mboard - if it has a camera icon at thestart of the line, click on that to see it's picture.
In any case, the part number of the mboard is listed - tell us what that is - xxxxxx-xxx.
Sometimes there is also a name HP gives to the mboard - quote that if it's there.


There is a 9 character part number for the mboard on a stuck on label on the mboard, if it hasn't fallen off - it often also has a bar code on it.

Tell us what that is.
If there is more than one, if you're not sure which one it is, quote all you find.

Sometimes there is also a name HP gives to the mboard - quote that if it's there.


These things can cause problems, but I have never had a USB device damaged because of them.

If the case is a brand name system case, they often have a one piece connector for the front ports on the case for connecting to a USB header on the mboard for two ports, or possibly two 4 or 5 in a row connectors, for the mboard the computer came with. The wiring of that or those female connector( ) works fine with the mboard the model came with, but it may not work fine with other mboards.

The wiring of which pin is for what in which position on mboard USB headers was never standardized.
The wiring of which wire in which position in a female connector coming from front USB portson a case was never standardized .

A particular mboard manufacturer tends to make the way of wiring up their USB headers the same for all their mboards made around the same time, but sometimes that changes as time goes by - e.g. that applies to Gigabyte mboards. Different mboard manufacturers don't necessarily use the same way of wiring up their USB headers.

It's possible in theory this problem could damage a USB device, but I have not had that happen when this was the case.

Some mboard USB headers, and some front USB ports on cases, have a fifth connection for one or both of the USB ports.
That fifth connection can be either another ground, or for overcurrent or similar - the two uses are not compatible with each other.
If you connect that fifth connection and the intended use on either end is different, you get an error message, often from the mboard, not the operating system, about overcurrent or the USB port being overloaded, or similar, sometimes even when nothing is plugged into the USB port.
This problem has done no harm to USB devices I have plugged into the affected ports, so you probably DO NOT have this problem.

The solution is to not connect the fifth connection.
- If the connector from the case is one piece for two ports, and IF and only IF the wiring of that is otherwise compatible with the mboard header, you have to either cut the wire or wires (usually it's one) that connects the front ports to the fifth connection, or insert something into the connector to bend a tab and release it's metal wire end from the connector so it can't connect.
- the two connectors from the front of the case are 4 in arow and 5 in a row, if the USB header has 9 pins, usually you can place the 4 in a row connector on the 5 pin side so the 5th pin has no connection, and the 5 in arowconnector on the 4 pin side, the 5th wire having no connection
- if the front ports have an individual with for the fifth connection, don't connect it to the mboard header.

hEy again!
Sorry i'd been away

Sooo now that you people have found out everything about my motherboard on your own :|

Wot else should i do now :-S
Because i just checked all the connections again by comparing it with the website too that you people posted :|
Still i get the same error :|
And one thing more, if i dun plug in the "shield wire", i dun get the error but also the usb doesnt work!
But as soon i plug in the shield wire And plugin the usb, i get the error then

Btw I have Intel Standard USB header Layout*

I would guess that you are making the connections wrong even though you feel they are right.

Many times the labeling for the case wiring doesn't match the board labeling.

You haven't provided enough info for us to conclude you're actually looking at the correct manual. Your mboard having an Intel main chipset doesn't necessarily indicate the mboard was made by Intel - most mboards with Intel main chipsets were not made by Intel.
Did you find the HP nine character xxxxxx-xxx part number on a stuck on label on the mboard that's for the mboard? If so, tell us what you found.

When the USB ports on the back of the computer work fine and the front ports on the case don't, the problem is almost always - 99% chance or more - you don't have them wired up properly to suit the particular mboard and front USB ports. If the front ports worked fine with the previous mboard, there's probably nothing wrong with the front USB ports or their wiring.
If you're absolutely sure you have the front ports wired right to a proper USB header - e.g. if the wires from the case are not labelled, the ground wire and the wire for the fifth connection are often the same color and it's easy to remove the wrong one when you think you're disconnecting the 5th connection - then the only thing left is the circuits on the USB header you have the front ports connected to are damaged - try wiring the front ports to a different USB header.
