    You could try this:

    Go to Control Panel > System > Hardware tab > Device Manager. Scroll down to Universal Serial Bus Controllers and click the + sign. Right the USB Host Controller and select uninstall. When asked to restart, click No, and then remove any other other Host Controllers if listed. When they have all been removed restart your computer. When the computer restarts, it will detect the USB controller and connected devices, and reinstall the drivers. You will probably be asked to restart the machine again, choose to restart, and you should be good to go.

    welcome to TechIMO, rocklee...

    which operating system? windows XP or what?

    try going to Start->Run, typing "services.msc" and then click OK. in the services windows, make sure that the "Plug and Play" service has a startup type of Automatic and that it's started. also check to see that the "Remote Procedure Call" (or "RPC") service is the same. make sure to restart the machine after making changes just to make sure.

    if those are both on automatic and started, then open the Device Manager. you can do this by going to Start->Run, typing "devmgmt.msc", and then click OK. once in here, make sure that you have a section called "Universal Serial Bus controllers" or else it won't work. other than that, reply back with anything that has a yellow exclamation point next to it. you can double-click on it and let us know what it says in the Device Status section.

    have you recently installed or uninstalled any software or hardware?
    have you been customizing your startup programs/services using anything, like maybe MSCONFIG or STARTUP_CPL?

    I just gave this link in another thread.

    This may help. http://www.nirsoft.net/utils/usb_devices_view.html

    Unplug all devices. Use the utility to uninstall all entries.

    You can highlight all entries, right click and choose uninstall. Just make sure no USB device is plugged in.

    Does any USB device work? Like a flash drive, or perhaps a USB mouse you have laying around?
    You could try and download a Live CD version of Linux to see if it's Windows or not.
    Ubuntu is a good version.
    Here's a link.

    no usb devices work
    im starting to think its a hardware problem and not a driver problem or something software related. i might install windows vista soon so hopefully that'll fix the problem with a fresh start

    sorry to hear it's still not working. definitely could be a dead bus... if the computer is a recent purchase or else under some kind of warranty, you may consider exchanging it.

    what software did you recently install? some types of software, especially those that allow you to mount virtual drives (like alcohol, daemon tools, etc) can cause weird device conflicts like this.

    make sure you do a complete format of the drive before installing Vista, or else you will likely encounter more problems. and make sure that all your hardware has drivers for vista before you do, or else you will have yet more problems. if it's all pretty recent stuff, then you shouldn't have an issue really. just check on the website of the manufacturer of each piece of hardware to ensure the latest drivers were released in '07 or else state that they are vista compatible.

    It may be a mis-wired bus or it died. When building a computer, sometime one might forget that the wiring is opposite and soon as you plug in a USB device, *Zapoooo!*. Be lucky if the motherboard doesn't fail either.
