Weird GA-P67A-UD7-B3 USB problem

Yes that's correct about having to disable one at a time to do the flash and then swap them over.

I'm having this very same problem on a Z68X-UD7-B3 build that I put together just three days ago. The only USB devices I have connected to the computer are a USB mouse (Logitech G9) and a "das keyboard" USB keyboard. The error message pops up seemingly randomly.

The system is non-overclocked and running Windows 7. I updated the board's BIOS to the latest revision, but the error persists. This is the first time I've ever seen the "power surge on USB root hub" warning/error message.

I hope the problem isn't with the motherboard, but currently my suspicion is leaning toward a hardware fault...

Hi

Try installing a PS2 keyboard and see if the problem still occurs. Another thing to try is disabling the USB3 controller.

Install Intel INF Driver 9.2.3.1016 and Intel Management Engine Interface(MEI) Driver 7.1.13.1088.

Thanks for the suggestions. Soon after posting my original reply, I discovered that the Renesas USB 3.0 driver I had installed was slightly out of date.  I uninstalled the older driver and updated to the newest Renesas USB 3.0 driver (2.1.19.0) ; perhaps this will stop the error message.

Install Intel INF Driver 9.2.3.1016 and Intel Management Engine Interface(MEI) Driver 7.1.13.1088.

I installed INF and MEI drivers that I downloaded directly from the Gigabyte website when I set up my Windows 7 install four days ago. I'm pretty sure they're the most current drivers, but I'll need to verify that. I'm currently out of the house and won't be back until the 14th. I will resume troubleshooting this problem as soon as I return and will keep everyone posted as to my findings, in case anyone else is suffering from this same annoyance. 

I'll just keep my fingers crossed and hope that this is something which can be remedied by installing the right drivers and that I don't have to do a complete system tear-down and RMA the board.

It turns out my INF and MEI drivers were out of date as well. After updating everything (Renesas USB 3.0 drivers, INF, MEI) mentioned in this thread, the "Power Surge on USB Hub Port" warning message hasn't reappeared. Hopefully the problem has been resolved.

At least that sounds hopeful now and there was a good reason for it even though it took a while to find it.

What exactly is the MEI driver? I've never installed it before, but I always install INF...

The Intel® ME software components that need to be installed depend on the system's specific hardware and firmware features. The installer detects the system's capabilities and installs the relevant drivers and applications.
For exsample, in ET6 without MEI you cann't change BLCK.

I think the USB power surge/malfunction issue might have been cleared up with the latest drivers and controller firmware. I've been running it for a while now and no messages. Can anyone confirm?
