I have a strange issue on a new build, concerning my Intel USB 3.0 ports. They seem to work fine for USB 2.0 devices, but my front panel ones will detect, show the contents, and then disconnect my USB 3.0 flash drive. I know of some issues with Intel's USB 3.0 controllers, and the solution (click here) to resolve them. I had to do so on my Ultrabook.
But this is where it gets strange. My rear USB 3.0 ports work fine with the USB 3.0 flash drive. I can move data back and forth at blazing speeds. It's just my front ports, which I thought were also controlled by the Intel chipset.
I have no issues in Device Manager, and all devices are installed (no unknown devices, etc). The front ports work fine currently with USB 2.0 devices, and I know they function properly under Windows 7 with the Intel drivers loaded. So, my question is this...should I follow the steps above, like I had to on my Ultrabook? I'm afraid of causing an issue with the rear ports, but I guess it is a simple enough rollback.
I'm just wondering if anyone has come across an issue like this concerning front ports. I would have expected all of my Intel ports to have the issue...not just the front two.
My board is a Gigabyte GA-Z77-UD3H and the case is a Corsair 300R.
