a doozy of a USB story
AArrgghh. My son plugged in a cheap mp3 player into my pretty new ASRock Extreme3 (see sig), into the front USB2 ports and managed to knock out the ports. They no longer work. Now I only see two enhanced controllers now in the device manager (but did not discover this until later). Fortunately the USB3 still works, and the USB ports in the back of the mobo work. I think those controllers are fried.
Before we knew the full extent of what had happened, we plugged the mp3 player into the front ports of my gigabyte system (listed in sig) and damned if it didn't shut down the computer. Just shut it down. We plugged it in again, and it shut down the computer a second time. Now I knew there was something very amiss. When I tried to plug a flash drive that I knew worked into the front ports, nothing, no response. Nothing was amiss in the bios re enhanced USB, i.e., it was still enabled. But two controllers were crossed out in the Win 7 device manager. However, after a few reboots, the controllers came back and work just fine. But not before my USB 3.0 controller was briefly knocked out as well. Geez.
But the Extreme3 is still messed up. I disconnected the connectors leading from those USB mobo headers to the front ports, but still, only two enhanced controllers show up in the device manager. Damned cheap mp3 player.
So, I'm open to any ideas. I've search the internet high and low for suggestions, but no joy. Are those two enhanced controllers somehow fried? I've never had anything like this happen before. I know for a fact that those controllers/front ports had been working just fine. Thanks.
