p8z77-v usb 3.0 header issues

post #1 of 5
Thread Starter 
The USB 3.0 ports for my case are plugged into the header on my motherboard. One of the ports works, the other one does not. All of the other USB ports function correctly.

I have two sets of USB 3.0 drivers installed, one for Intel and one for Asmedia. The Asmedia drivers were reinstalled from the motherboard cd; I could not find Intel drivers from an external source (Asus cd or intel.com) that were compatible with Windows 8. I uninstalled the Windows 8 native Intel USB 3.0 drivers and reinstalled them through the device manager.
Quote:
Windows 8 has native in-box USB 3.0 driver. Intel is not releasing a specific Intel USB 3.0 eXtensible Host Controller driver for Windows 8.

I previously had a Lian-Li PC-B10 housing this computer that had the same issue. The Lian-Li case was using this IO port kit.

This is not a major issue, as I don't actually think I've ever needed both of the USB 3.0 ports on the IO panel at the same time. It is, however, bothersome to know that it is not functioning properly. Any help would be greatly appreciated.

There are two USB 3.0 ports plugged into the same mobo header. One works great, the other does nothing when plugging in either a phone or a flash drive. The previous case also had two USB 3.0 ports plugged into the same mobo header with the exact same issue, so I very seriously doubt that my issue is with the physical ports or cables.

I suspect a software issue, but can't seem to fix it. I'd rather not nuke and rebuild the whole system over one stupid port. : /

I mean the header on the motherboard might be at fault. what if you uninstall all usb drivers than try to re install them using the asus software. It should than download the latest drivers available.

Thats all I can think of atm I hope it helps thumb.gif

Edit: I like your build thumb.gif

I think you're right. I tested the ports with the computer off and still only one of the two functions, so I think that rules out driver issues. My next step is to talk to asus.

It just seems wierd that one port would function fine when they both are plugged into the same header.

Thanks. smile.gif I've had a lot of fun building it and learning to overclock on it. A little sad nvidia seems to be about to drop the 700 series though, since I just picked up this second 560 on the belief that they wouldn't until at least the end of the year...
