USB ports not working, but still have power...
Posted on 2009-02-21
I have an EVGA nForce 650i Ultra motherboard and none of my USB ports are recognizing anything I plug into them in Windows. The ports still have power however since I was able to charge my iPod and when I plug in my external hard drive, the power light comes on. I do not get an error message. I have done the following troubleshooting so far and nothing is working:
* removed all instances of USB devices in device manager and re-booted; they re-installed but still no luck
* shut down and unplugged PC for a minute or so and re-booted
* re-installed my chipset drivers
* I downloaded and ran USB Verifier (USBCV R1.3.2) from usb.org and am getting "Test suite failed" and the following data:
Microsoft Windows XP (Build 2600)
Service Pack 3.0
USBCommandVerifier.dll ver 18.104.22.168
TestServices.dll ver 22.214.171.124
StackSwitcher.dll ver 126.96.36.199

If you are testing a full/low speed device, please connect the device to a USB 2.0 high speed hub and connect the USB 2.0 high speed hub to the USB 2.0 host controller on this system.

I have XP SP3 and all current updates installed. I realize that the USB functionality on the motherboard could be broken, but before I can accept that, I'd like to make sure I have tried everything.
Any assistance would be appreciated. Thanks in advance.
