I bought an asus p8z77 v pro but the intel usb 3.0 ports aren't working:( 
First i installed the driver on the cd, then it worked but as soon as i installed the asmedia drivers they stopped working...
I reinstalled the intel drivers but nothing happened.

Get a USB stick and plug it into your PC. Use -> TOOLS-EZ-Flash

Download the latest bios for your motherboard and unzip the .ROM file to the root of your USB stick.

Restart your PC, enter the BIOS, go to TOOLS-EZ-Flash, and if it is all working ok, you should see the contents of your USB stick listed.

Select the .ROM file, then follow the on screen instructions.

When it has finished, it will ask you to restart your PC.

Observe same issue with my new build. Also P8Z77-V Pro. USB ports quit after installing drivers. Curious on your success to date.

In my case also notice that Win7 Pro (64 bit) made its updates. Cannot say it was Asmedia install or Win update. Tried uninstalling USB drivers and reinstall with Asus downloads (rather than detect hardware with windows). No success.

The solution is simple:


Still have problems? Try the 100% Guaranteed ErrorSmart for free!

1. Unplug (not just turn off) you PC.
2. Unplug all your USB devices from your PC (and, heck, any power supplies as well)
3. Wait 30 minutes or more.
4. Plug in your essential USB devices (keyboard, mouse).
5. Plug in your PC, turn it on.
6. Pop in the rest of your USB devices.

I also had the same issue, with a P8H77-V motherboard. In my case I have an internal USB 3.0 card reader that I have plugged into the USB 3.0 port on the motherboard. After my initial build, the card reader was working (power light was on, device manager listed a bunch of storage devices, and I was able to download photos off a CF card), but then after a Windows Update it stopped working (power light was off, device manager listed the USB 3.0 port as "working" but it had no storage devices).

Here are the steps I did to get it working again. I don't recommend that you repeat them all, but hopefully it helps someone else solve this problem:

- In Device Manager, uninstall the USB 3.0 driver.
- Insert Asus driver disk and reinstall the driver.
- Reboot.
- Observe that the device still doesn't work.
- Power off the machine and unplug everything.
- Open it up and unplug the card reader from the motherboard.
- Plug the card reader back in, but notice that it doesn't seat properly.
- Unplug it again and notice that you bent one of the pins.
- Swear a lot.
- Carefully bend the pin back and carefully plug the card back into the motherboard again.
- Unplug it again in a paranoid attempt to make sure you didn't bend another pin.
- Carefully plug it back in again.
- Attach the power cord, the monitor, and the keyboard, but nothing else.
- Boot the machine and observe that it still doesn't work.
- Get frustrated browsing the web with just the keyboard and decide to plug in your mouse.
- Accidentally knock the monitor cable off the video card in the process.
- Plug the monitor cable back in and notice that your stupid monitor no longer wants to show you anything except an error message about an invalid input format.
- Press the reset button.
- Observe that nothing happens. Strange. Aren't reset buttons supposed to reset the computer? I will have to try that again one day.
- Press the power button, and observe that the machine shuts off.
- Tap a key on the keyboard and the computer comes back on. Hmmm. Was the computer just asleep, or does this motherboard have some sort of boot-on-keyboard function?
- Observe that everything is magically working again, seemingly no thanks to anything you might have done.

So, I'm not sure if this is helpful or not, but this is what I did to solve the problem. I'm betting that this thing is going to stop working for me again one day real soon and I'm going to be quite annoyed again.

I'm having the same problem, the front panel has 2 USB 3 Port and 2 USB 2 port which all have been correctly connected to this MB. They all working at USB 2 speed when I put on my USB 3 drive. However, the two USB 3 port at the back just doesn't recognize the device at all.

The only thing I can learn from there is power off and do a "Normal" Reboot which I still haven't tried and wasting my time reading here.

I had the same problem, the culprit is that some of the USB 3.0 ports on this mobo use the intel driver, and some use the "Asmedia" driver. Install both off your mobo disc and everything should work fine.

I have the same board as stated by the OP. I have not tried the method I have posted, but it seems to work for some people. From what I understand Windows 8 is using it own built in XHCI host controller software and USB stack.

While this brings some benefits like UASP support, there are some devices that currently don’t work with the Microsoft stack on the Intel USB 3.0 host controller. This can be fixed by forcing Windows to use the Intel USB 3.0 host controller drivers instead of the built in stack.

Here is a link that might help:

http://plugable.com/2012/12/01/windows-8-and-intel-usb-...

*NOTE* These instructions are only for machines with an Intel eXtensible Host Controller. Look for the Intel(R) USB 3.0 eXtensible Host Controller under Universal Serial Bus controllers in Device Manager.

Is your mouse and/or keyboard a Razer model? If so then use them in the usb 2 ports. If you really need to use the usb 3 ports then select either the keyboard or the mouse but not both.

The Asmedia controllers are better supported for Windows 8 rather than earlier versions such as Windows 7.

Only use drivers from the Asus support site so you need to select "Choose what drivers to install" rather than the"instal updates automatically".

I know this is an old thread but there's not a lot of solid answers for this problem online so I wanted to post it out here in case someone else stumbles on this issue. I just got this working on my machine last night after hassling with it for 2 hours. From what I've seen online there can be three issues you may be experiencing if your USB 3.0 ports are not working:

1) You may have a hardware issue. This is less likely... To determine if it's hardware related, plug something into the 3.0 ports and see if it gets power... if it does then you have a software problem. Otherwise you may have a loose wire or a burned out board - in that case I'd take it back from where you got it and use your warranty to get a new MOBO.

2) You may have the ports disabled in the BIOS UEFI. Again this is not likely as your default settings has both 2.0 and 3.0 USB ports enabled. To check:
a) Jump into your BIOS during start-up (for me it is the delete key)
b) Go to advanced options
c) Go to the advanced tab
d) Click on the USB option and verify that both 2.0 and 3.0 ports are 'Enabled'

3) You have a driver issue. This was my problem as I found out that the drivers that come in the box are out of date with Windows 7. Finding the correct drivers from Intel or Asmedia can be a royal pain in the a$$ so I would recommend going directly to the ASUS homepage: http://support.asus.com/download.aspx?SLanguage=en&m=P8...

a) Once you enter your OS, you'll see a drop down that says USB, go ahead and download all new drivers and download them to your PC. You can go ahead and unzip them as well but DO NOT INSTALL YET.
b) IMPORTANT: If you are using Windows 7, you'll need to make sure you have the latest Windows updates on your machine. For some reason the Intel drivers don't like the out of the Box Windows install... it wants to see some of the hotfixes included in the Win7 Service Pack 1. Otherwise you'll get some generic error telling you that your system does not contain prerequisites for the driver update.
c) BEFORE you install your drivers, go to your Device Manager and uninstall any USB drivers with a yellow triangle and an exclamation point (just right click on them and remove/uninstall is one of the options). These are your previous drivers and there is a chance that they can interfere with the new ones.
d) Now that you are fully prepped you can go ahead and run all the driver installs (I had 4 updates). Ironically it was the Asmedia drivers (not the Intel) that were my problem.

With each install, you'll need to reboot your machine, and then you should immediately notice a response from your USB3.0 ports.

Good Luck!

I know this is old but i think i have found a solution:

Do this:

Start > Control Panel > Device Manager > look for a category labeled 'Other Devices' > inside that look for a device named 'Unknown Device' > Right Click on it and click 'Update driver software.

That should fix the problem

That worked for me. I really thought it wasn't going to work because it seemed too simple, but it did. Thanks a bunch
