MAXIMUS IV EXTREME P67 USB 3.0 Ports Not Working

[Retired]

Hi Guys,

I've just recently (2 days ago) built my new machine using the mobo mentioned in the title and have just realised that 4 of the 3.0 slots do not function. the 4 nearest to the PS/2 connections.

I have tried updating the bios, chipset and have reinstalled Windows 7 Ultimate (64-bit) but it still persists.

I have a Haf X with 4 ports on the front that work fine so could that be why? my friend tells me that it shouldn't affect the mobo USB slots so i'm a bit worried.

Any help would be greatly appreciated.

Thanks,

James

In my case I solved by doing this:

1. Attach your keyboard mouse to the USB ports on the face of the board (i.e. the place where you plug in your case’s front usb ports, attach your stuff there. Also you can use the extension that comes with the board).
2. Uninstall your 3.0 USB software. Do this by going into device manager, scrolling to the bottom and expanding the tree labeled Universal Serial Bus controllers. right click and disable then uninstall each driver labeled USB 3.0
3. Shutdown
4. Unplug everything from rear panel USB, have nothing attached to the rear panel USB ports.
5. Press and hold the CMOS button on the rear panel for 10 seconds to reset the BIOS (your computer should be off)
6. Power on the computer with a fresh BIOS (you can go into the BIOS to save the fresh one if you want)
7. Start up everything (no USB on rear panel yet)
8. Install the software FROM THE ASUS SITE
9. After installation you can now plug things into the rear panel
10. Setup your BIOS as you wish back again.

So I called Asus Motherboard support on this issue, and had them read through this thread. Asus believes this is a power instability issue, something that cannot be fixed by drivers or settings in the bios. So, if you are suffering from intermittant USB support, call ASUS and RMA your board. Don't waste anymore time trying to fix something that can't be fixed.

I am a great beleiver in waking up old sleeping threads, and also because I Have the same problem

I have done the firmware flash to 4.0.21 worked like a charm to flash them
and installed the latest renesas drivers 2.1.39, easy enough
shut off in power management as recommended
changed to NEC in the bios

BUT

Still cannot get them to work at 3.0 speeds.
any IDEAS anyone out there, im going crazy

I hope its NOT what the poster before me says, about the power issue
Im hoping someone somewhere out there has solved it, and ive just not found it yet..

I subscribe to the thread, so any answer, will hit my email directly.

thank you

Hi
All my issues were solved after installing Win 8.1
All USB 3.0 ports work fine since then, that was over a year ago
also remember i had done the Flash before

Any official advice yet? It's scandalous that a high-end motherboard has this kinds of problems on such a large scale. I've read multiple threads about this problem and have yet to see an official response.
