USB device overload

[tommy6000009]

Hi,
I'm wondering if anybody can give me a solution to this problem. Previously I had a MSI motherboard and found out it wasn't compatible with my CPU as it needed a bios update, despite the webpage saying it was compatible, so swapped to ASUS H81m-plus. Rather than buying a processor to do the update(the cheapest was £50) I bought a new motherboard(the above-mentioned). All went well this time, it came on straight away after I had built it but then I got an error message, explaining that the PC would switch off after 15 seconds. Something like 'USB device current overload detected'.
I've searched Google for answers but nothing has helped. I've tried removing the USB cable from the motherboard, straightened pins that I noticed were bent(USBSW), taken out the(can't remember what it's called, the metal thing which the the motherboard connections go through, which I had to attach to the case, with those annoying pieces of metal you have to remove). I've also tried taking all cables out and inserting them again.
Perhaps somebody with more knowledge than me has any ideas?
Many thanks Thomas

Sounds like one of your USB ports are damaged and are connecting with another.

Strange that removing the USB header from the board didn't help - normally it's a case USB port that gets damaged.
In this case, I would suspect the damaged port is directly on your motherboard - on the back of your case.

Disconnect power and examine all your USB ports, you'll probably see one is "mangled" for lack of a better description.
A pair of tweezers should be all you need to straighten everything out. Once they look right, reconnect power & see...

Thanks for your response. I don't have any bent pins. I've looked in all the USB ports and they all look fine also. You mentioned the back of the motherboard - you think there could be damage there?

Do you think a bios update may help? I put the latest bios version on a USB stick, as I wanted to try to reset the CMOS by taking the battery out.

One of the USB ports on the back of the motherboard, yes. If you still have the issue after removing the cable from the header (that connects your case USB), then you have to look for more USB ports. So the ports on the back of the board are a likely place to look. Have you inspected those also? On rare occassions, the plastic piece of the USB port comes out - remaining attached to the USB device that was plugged in, so that's a possibility too.

Doesn't sound like a BIOS issue, so I wouldn't think a BIOS update would fix the problem. It sounds like a USB port is physically damaged.

I haven't connected any USB devices yet, apart from a wireless USB for mouse and keyboard but I connected that to the case USB.

I'll have a look for physical damage to the other USB ports again but when I looked last night I saw nothing. What do I do if they are physically damaged? Is returning the motherboard my only option, if that's the case?

It really depends. Bent pins can usually be straightened out yourself.

The I/O shield that you inserted in the case may also be causing the issue but shorting the USB ports.

I would go back to basics. Remove your motherboard & place it on the box (or similar) to avoid static buildup.
Mobo + CPU + HSF + 1xRAM + PSU connectors & see if it's responding at that point. If so, you can then look to the cause as the problem component.

I removed the shield last night and had the same issue. I guess the USB port damage is the likeliest answer as you say.

I'll have a look soon. I've a screaming baby in my face at the moment.

It sounds the most probably. If you could post a picture of your USB ports, I could see if I spot anything.

Thanks. I'll post a photo later. Wife has dragged me shopping.

Sorry about quality, it was the best I could do. Can you see anything wrong?

Hmmm, nothing looks damaged on the outside. I'm not very sure to be honest. Let me have a think
