Hi Guys,

Hoping you can help with this.

I have the above listed mobo with an Cooler master HAF 932 case that has 4 front USB panels. Now previous to today, everything was working just fine, then I installed some windows updates.....my mistake I guess.....

Now nothing is being recognized from the front USB's, and initially even the rear weren't being recognized. I rolled back to a restore point, reinstalled the chip set drivers for the board and got the rear USB working, however the front still are not cooperating. Thoughts??

Any help much appreciated

The front USB 3.0 ports are provided by the Intel Z77 chipset, so normally are the best for use than the add on USB 3.0 chip.

What OS are you using, and any idea what the updates were about? Strange the restore point did not fix both sets of USB 3.0 ports. Checking the cable to the front panel and trying a USB 2.0 flash drive or mouse or keyboard in those ports to see if they work at all is a good test.

Checked the cable - all good

OS - 64 bit Windows 7, Home premium

Drivers - Windows update says generic windows 7 updates, however when I went to system restore it curiously said 2 of them were drivers.

We don't know what USB 3.0 drivers you have, which are required for Windows 7.

That driver may not be your problem, but is worth a try since installing it is simple.

You should also check Device Manager in Windows, the USB entries are at the bottom of the device list. Double click on any entry that has a yellow '!' next to it, indicating a problem. Even if you don't see any, opening the USB 3.0 entries allow you to check the driver and might provide some other information.

I wonder if Windows update slipped in some strange change, that happened recently on an unrelated situation.

You can try installing the Intel USB 3.0 driver yourself. You have two main choices. One is the Intel USB 3.0 driver from your board's download page:

http://www.asrock.com/mb/Intel/Z77%20Extreme4/?cat=Download&os=Win764

Or you can use the latest version Intel provides for your boards Z77 chipset, here:

https://downloadcenter.intel.com/download/21129/USB-3-0-Driver-Intel-USB-3-0-eXtensible-Host-Controller-Driver-for-Intel-7-Series-C216-Chipset-Family

The file from Intel's website is a newer version.

How do you know the cable is good, from a visual inspection? The connector for USB 3.0 headers on a mother board aren't the greatest design, and can easily become loose. I literally tape them in place.

Yea unfortunately neither of them worked. I unplugged and plugged the cables back in inside the case. I guess Ill just work around it and buy a USB hub for more ports, it's a minor inconvenience, but I was hoping to get the front ones back up and running.
