    My wife was recharging her Ipod on my computer and after she finished, I noticed that my computer was frozen. I rebooted by using the restart button and it restarted without any Windows error messages However, all of the USB ports were gone. (If I plug in a memory stick, it lights up, but is not recognized.) I tried un-installing all of the USB contollers and rebooting, but the ports still do not work. No errors appeared under each controller in the device manager ("the device is working properly") I suspect it's a motherboard problem. Is there anything else that I can do to diagnose the problem?

    Thanks!

    is there a reason you suspect it is the motherboard? because its not likely that the usb portions of the motherboard just failed out of the blue and there are alot more things that are likely to die before the usb's. I think hardware wise you are fine. You said you uninstalled the drivers? Then you need to reinstall them.

    I suggest doing a windows update. you can go to control panel. and on the left click windows update. then when you get the option click custom. then once it loads look to the left for high priority and ***hardware*** updates.

    also, when you plug in a usb device and it doesnt recognize it or does nothing at all, you can try going to device manager, right clicking on the USB heading and clicking scan for hardware changes. that usually works for me.

    I un-installed the USB controller devices and they were reinstalled when the machine was rebooted. Is that the same as uninstalling the drivers?

    I went to Windows update, but there were no hardware updates for my machine. My machine has all of the critical updates.

    I tried right clicking on the USB heading and scanning for hardware changes, but this made no difference.

    Any other suggestions?

    There are no yellow triangles in device manager.

    I installed the USB window port patch from the ASUS website and rebooted, but nothing changed.

    I also checked the bios at start-up and the USB is enabled.

    Were you referring to the registry fix or the USB PCI adapter? I'm a little wary of playing with the registry, since I don't have any experience working with it. Buying an adapter might be a better way to go. They are not expensive (about $20 or so) and there is little risk associated with installing them. I've seen a couple of other posts where an adapter fixed a similar problem. But I sure would like to figure out what is wrong with my computer's USB ports and want to be sure that it's not a symptom an underlying problem that going to cause me grief later.

    I was referring to the registry fix. Just as long as you back up each key you change, set a restore point, and follow the instructions carefully, you should be fine.

    I checked the registry and the device path does not need to be modified.

    well the only other optionss i can foresee are going and re-installing windows or buying an adapter. i think tha adapter would do you better. i dont think its an underlying problem with the hardware thats causing this and i have no more ideas as to what software related problems could cause this; therefore im going to request an administrator move this thread to software.

    My computer just rebooted as I was reading a thread. Are you sure that it's not a hardware problem?
