    Thanks for the updated brief. By all means it should not appear twice as you may know.

    I think you may have a few things going on here. Your USB controllers may be messed up. "Overloaded with registration data to manage" so to speak. This happens when we insert USB devices in various slots instead of using the same. Mostly a Registry overload. The other may be the wrong driver for your phone, but we will see.

    You may want to look at this to get glimpse: USB Device Registry Entries (Windows Drivers)

    Let's see if we can find a tutorial, fixit, or a troubleshooter to fix it.

    FYI, USB3 ports are usually blue whereas USB2 ports are black. Might depend on OEM, so you may want to check on the Dell site or your manual.

    I attempted to run the Windows USB Troubleshooter but got this:

    I looked at the USB Device Registry Entries page...

    1. Find this registry key and note the DeviceInstance value:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\
    In that key there is no value DeviceInstance - only the (Default) value.

    2. Find the device instance registry key and get the device interface GUID:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\<hardware id>\<instance id>\Device Parameters
    I drilled down into all 17 subkeys and none had the value DeviceInterfaceGUID.

    3. Under the device instance key, note the device class, subclass, and protocol codes:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB
    The class, subclass, and protocol codes are available in case I need that data.

    Does that give you any clues - or - what should I try next? (I really appreciate your time and trouble)

    You're welcome. Glad to help as much as I can.

    Do you use a Registry cleaner?

    Obviously you see the USB Controller in Device Manager, yes? It may be corrupt drivers as well. Haven't had trouble with USB since 8.1. I've uninstalled all USB Hubs one by one before (expand USB Controller > right click every hub > uninstall), then rebooted in which it reinstalls the drivers and corrects everything in the Registry. That's worked for me in the past.

    Trouble is, when uninstalling you will loose any USB mouse or keyboard to reboot with, unless you have a reboot button on your tower. You can do it with the standard PS/2 port mouse or KB if you have one around.

    It's either that, or a Repair Install of Windows 10 with an In-place Upgrade: Repair Install Windows 10 with an In-place Upgrade Installation Upgrade Tutorials

    That's the only fixes I would know of.

    No. Should I be using one?

    Yes, that's the first thing I looked at after reading your previous post. No yellow ! icons, though.

    This machine doesn't have PS/2 ports. Wouldn't it work to do a hard reset with the power button?

    Could I uninstall then manually reinstall the drivers? I could control the machine remotely with TeamViewer.

    Absolutely not. One of the worse utilities to use. In fact, I stay away from any 3rd party fixit/tweak it programs. All that is needed is in Windows already. Just have to learn them.

    That's what I figured.

    Not sure, for that's like a power loss or pulling the plug. You could try it.

    Good idea. Try that if the hard reset doesn't work. Good luck.

    I manually uninstalled the drivers then rebooted and that worked ... until the next time I connected my iPhone a week or two later. (I believe I got my words mixed up with what I wrote previously: "Could I uninstall then manually reinstall the drivers?").

    So twice I repeated manually uninstalling the USB drivers and rebooted, but this time it did not work.

    I ran the Windows USB Troubleshooter and got the result "USB controller is in a failed state or is not currently installed..." just like the screen shot above.

    Is there a way to manually install the USB drivers?

    Hi again, ixodid. There's got to be something more wrong than just USB problems.

    Highly recommend this using the keep my files choice. Make sure you back all important files up first: Reset Windows 10 Installation Upgrade Tutorials

    You've been gone awhile, so in refreshing my memory > Did you upgrade to 10 originally from a prior OS? How many times has it had feature updates? And which edition and version are you on?

    Edit: You show 10 and 7. Are you dual-booting?

    I was afraid that would be the recommended fix.

    Did you upgrade 10 originally from a prior OS?
    No, 10 came on this Dell desktop when I purchased it Jan. 2017

    How many times has it had feature updates?
    Sorry, I'm not sure what you mean by that

    And which edition and version are you on?
    Home x64, 10.0.16299

    Edit: You show 10 and 7. Are you dual-booting?
    No dual booting. One machine is 10, another machine is 7 (actually three 10 machines and two 7 machines).

    Thank you again for your help - I'm very grateful.
