I don't know if you guys remember or not - but a while back I was trying to fix my front USB ports. I found the fix, if anyone is interested.
DiagnosisYou have just built your system, installed a fresh copy of Windows and installed all your drivers. Try as you might, USB 3.0 on your case will not work.
1. USB 3.0 cables only : No response
2. USB 2.0 cables only : ports function as USB 2.0
3. USB 3.0 and 2.0 cables together: Windows doesn't recognise devices
To confirm you have the same problem. Test to see if your USB 3.0 ports on motherboard itself are functioning correctly. If you have the same problem they will either get no response or they will run at USB 2.0 transfer speeds.
HypothesisChances are, when you installed Windows you had one or more USB devices plugged in while you were doing it. Probably a USB keyboard and/or mouse. Because of that, Windows has installed a generic USB controller driver to allow you to use those devices in windows.
When you try to install your motherboard's USB controller drivers over that, they are not overwriting the ones that windows has installed.
SolutionYou need to delete all the USB controller drivers on your system and reinstall them.
Step 1 - Find/borrow a PS/2 Keyboard and plug that in.
Step 2 - Activate
Mousekeys.
Step 3 - Unplug all your USB peripherals
Step 4 - Go into Device Manager, expand the Universal Serial Bus Controller section.
Step 5 - Uninstall everything under that section.
Step 6 - Reboot.
Step 7 - Reinstall your USB drivers as provided by your motherboard manufacturer.
Step 8 - Reboot as instructed.
You should now have fully functional USB 3.0 in the front and back. Ensure that only the USB 3.0 cable from your case I/O is plugged in (ziptie up the USB 2.0 controller for tidyness). Disable mousekeys and enjoy your Bitfenix build! :)
