My case (ThermalTake AMD Edition) has a front panel with one USB2.0 port and one USB3.0 port. My motherboard has no USB3.0 headers (but two USB3.0 ports in rear). I have had the single USB2.0 front panel port connected to one of the 6 available internal header ports and was unhappy with only one of my case ports working. I installed a new USB3.0 PCIe card with 2 external and 1 internal USB3.0 port. I connected the front panel USB3.0 to the new header on the card (and also connected the 4-pin molex power connecter on the card). While I was rerouting these 2 wires, I unplugged a few of my other cords to reorganize, one of which was my front panel USB2.0 port connector.
I hooked everything back up, was pleased to find that the USB3.0 front panel port now works, but dismayed to find that my USB2.0 front panel port DOES NOT WORK ANYMORE. I pulled out my motherboard instruction manual to verify that I had the pin order correct - it is. I tried switching to a different one of the 6 available pin sets. Still no luck!
I don't get it! Help?
