Windows 7: Power surge on USB hub port...

Power surge on USB hub port...

My system, see specs for details, started to popup this error message:

"The usb device exceeded the power limit of its hub port"

Clicking on the message brings up this window:

Name:  USB.PNG
Views: 6
Size:  52.9 KB

There are two USB devices plugged in to the computer, keyboard and mouse in the USB 2.0 ports, when the message pops up. The same keyboard and mouse had been used for years without any issues. The Dell keyboard does have two USB ports, but they are not used.

There's nothing to disconnect and selecting the option of "Reset" in the above image does not fix the issue. The keyboard and mouse does work just fine during the reset. While the eSATA should have no relation to this issue, disconnecting the eSATA external drive did not fixed the issue either.

Since the issue does not relate to and actual device, it seems that the motherboard's power delivery (capacitors?) could be the reason for the error message. Is there a way to check this power delivery?
TIA...

I would check first with another keyboard and mouse. One of the present ones may have started drawing more power than normal. Quite possible.

Thank Jumanji...

The keyboard and mouse are fine, tested with different one and the power surge is still there.

I've disabled the offending USB hub in the control panel and there's no more power surge error message anymore. Unfortunately, this hub handles the front USB 3.0 ports and as such, no more easily accessible USB 3.0 port on the case. The USB 3.0 ports are still working in the back.

Interestingly, disabling the front USB 3.0 ports didn't fully disable the ports. They still work as USB 2.0 ports and Windows 7 warns about plugging in the USB 3.0 device into high speed port, which it didn't do prior to this issue surfacing...

If it is a recently released motherboard, you may check with the manufacturer if it is a known issue.

A recent Intel motherboard had a power surge issue. Intel support acknowledged it as a known issue and modified the USB connections in the next version. I do not overrule a similar issue in the Gigabyte board, whether acknowledged or not yet acknowledged.

So, in my perception, you may do well to take up the issue with Gigabyte support.

Taking it up with GigaByte's tech support could take some time. After two days, the status of the ticket is still "The email will be processed". Way to go Gigabyte...
