    For the unknown device: right click on it > left click properties > click details tab > in the properties bar choose hardware IDs > make an image to post into the thread and copy and paste the results in the value area into the thread. Then search the internet using the information in this link for the information about the driver:

    How to easily find drivers for Unknown Devices in Windows | PCWorld
    How to Find Drivers for Unknown Devices in the Device Manager

    Open the HP website > enter the computer's product or serial number > view available drivers > update the HP UEFI hardware diagnostics from version 6.4 to either 6.5 or 6.6. If the up to date version is not listed in the available driver use this HP link:

    Here is a shot of HP Diagnostics 6.5. Seems OK.

    And Device Manager. Note that the unknown driver is listed but the yellow flag is not there. There is no reference to the driver.

    I've seen this kind of thing before, and it usually occurs when a USB driver issue somewhere between the end device (usually a drive, a USB stick, or something similar) and the root hub gets flaky. If you run Uwe Sieber's USB Device Tree Viewer, you'll see something like this:

    This will help you zero right in on what's in port#6hub#2 that's "gone missing."

    Downloaded the USB Device Tree Viewer. Remarkable. Port6 under USB 3.1, Intel(R) Wireless Bluetooth(R), might be it. I have no Bluetooth devices. I'll just leave it alone.

    Good tip!

    Might just be that BT is turned off (hardware)?

    If you're not using BT, doesn't matter anyway -- as you already said yourself. Glad the tool helped you pinpoint the (non-)problem. That's what it often does for me, too, FWIW. Thanks for following up and telling us what you found. Best wishes for placid computing in the future, too!

    It was a guess, but this may well tell you for sure.
