  • Unknown Devices in Control Panel

    After many failed attempts to install an external faxmodem because it was not compatible with my OS Windows 8 64bit I have 4 unknown devices in my control panel which I have now discovered they are related to Dell Wireless 1703 Bluetooth pre-installed with my New Dell XPS 8500. I have uninstalled these unknown devices and even Bluetooth to get rid of them - they disappeared but on re-boot or restart all appeared again - Bluetooth and the unknown devices which now seem to have been integrated with Bluetooth are without a driver (Code 2 but details of drivers are:
    Bluetooth' driver is working properly.
    Could anyone please inform me what to do to get rid of these unknown devices?
    At present I don't have a Bluetooth hardware device - all I have is the software ready for Dell Wireless 1703 Bluetooth..

    Try a system restore.

    If for some reasone System Restore can't help, then try Windows update to find the drivers
    Or go to DELL Drivers and Downloads website. There you get a list of all available drivers for the default buildin devices on your computer model.

    If you still can't install the drivers and you actualy do not use the devices anyway then simply Disable them in Device manager.

      If you have the software for the devices on your PC, right-click them in
      Device Manager and select "Update Driver Software." This will allow you to either search automatically for driver software or browse to it's location manually.

      Search automatically will check the Net as well as your local PC.

      Good luck!

        If the devices keep showing up as unknown after a reboot that means there are actual hardware devices that don't have their associated driver installed on the computer.

        Your options are to install the drivers or disable the hardware since it sounds like they're integrated into the computer.

        You should download the drivers and software from Dell's set. If you have support then they can tell you exactly what is in your computer and which drivers you need. You can also look up the original system config or allow Dell to scan your computer from their support site.

          If you don't want them, then it may be necessary to disable them in the BIOS. that way Windows won't see them, so it won't need the drivers.

            I've had similar issues with Dell computers that we have at work. Of course, with Dell it's pretty easy to see what hardware drivers you actually need.
            There comes a point - when your computer is 5-10 years old - where Dell doesn't provide the right drivers anymore.
            My solution: download the Vista drivers and install them!

            Also, these old machines don't always the corrent list of drivers if you look by Service Tag, so instead of looking for the particular machine, browse for the model of computer and you'll find a heck of a lot more drivers.

            If you install a driver for hardware that doesn't exist, you will get a message that the hardware wasn't found.

            Then again, if you're having a bluetooth device for which no driver is installed - and you don't use the hardware - just leave it be and stop worrying!

            Another tip: some hardware (onboard) doesn't show up until you install the correct chipset drivers!

            Don't know what hardware you have? Open the computer, note down the numbers on the chips and google them! You'll see exactly what you have in your rig.

              Run this script and it will remove all unconnected devices. I use this to clean up any P2V's servers and it works a treat.
