USB 2.0 ports randomly stop working

[MasterOfUnlocking]

Hi,

I have the following problem. I have an Asus P8Z68-m pro motherboard with a 2600k and 12 GB ram. Sometimes when I start up my computer the USB 2.0 ports stop working while the 3.0 ports still work flawlessly. I then have to reinstall the intel chipset drivers to make the 2.0 ports work again. Needless to say, this is very very annoying. I am using the official drivers from the Asus site, by the way. Any idea how to fix the problem so that I don't have to reinstall the drivers all the time?

Did you try updating the BIOS? I updated mine, minutes ago and it solved some silly overclocking limitations for me. If you need I can explain how to do it, since the asus site is a bit vague.

Otherwise, what are you trying to connect to that usb port? Did you try multiple USB devices, like keybards, USB flash drives and such to see if it's really the issue with the mobo?

Thanks for the reply. I have various devices connected to my USB 2.0 ports, among them keyboard, mouse a powered USB hub and a bluetooth receiver. I am a bit reluctant to update the BIOS but I might have to do it if it is absolutely necessary.

I was reluctant at first as well, though it proved to be simpler than I expected.

Anyway, what is usually connected to the problematic usb port?

Well, it's not just one port that stops working. It's all USB 2.0 ports. The 3.0 ports still work without any problems.

Hmm, did something specific happen when USB ports started malfunctioning? Thunderstorm? Suspicious software install? Windows update?

You can try to do a system restore as far back as possible, if that doesn't work, your only real option is to update the BIOS, besides reinstalling the drivers.

Try blowing in the USB holes, sometimes dust prevents them from working properly.

But not all of them at once, that's the strange part.

OK, so I updated my BIOS which kinda screwed up my Windows installation . But I hope I won't have any more problems with the ports now :)

That shouldn't happen. But it cant hurt to reinstall windows from time to time.

Yeah, I found out that the new BIOS set all my old resettings on default and I had to change my hard drive settings from AHCI to IDE again to start up windows again. Anyways, thanks a lot for you suggestions, I hope it works now :)
