    Unknown device in device manager

    philly4

      I just did a fresh install of windows 10 pro 64 bit and after installing all available drivers from intel driver page for my NUC model (5i5RYK), I still have an unknown device.  The CIR driver wouldn't install so I thought that must be it, but the unknown device still shows up even when I disable the CIR in bios.  Anybody else seen this?

      Thanks.

          Uninstall the device, it will probably reinstall as a USB device very briefly. If so make sure you have the latest USB driver and reinstall the USB driver.

            When I do that, it disappears until I click "rescan for new hardware".  Where can I get the latest USB driver?  I've installed everything on the Intel Driver page for my computer.  Thanks.

              Don't use the drivers in the roll-up file. They don't appear to be as recent as the individual drivers. Look for the latest(make note of the version numbers/dates). I think the USB driver may need more than one install pass to pickup all of the hardware. That was the case with my i7.

                unimorpheus,

                 

                Can you please elaborate what you mean by the "roll-up file"?  I don't think I ever used the roll up file but I'm not exactly sure what that means.  I installed the drivers for Windows 10 here: Intel® Download Center

                 

                Also, this issue seems to be intermittent.  I did another clean install of Windows 10 and after installing the chipset drivers, I didn't have any unknown devices.  After running it for two days now, I just looked and it was back.  I re-booted and it was gone again even after "searching for new devices".  Could this be a hardware issue?  I noticed similar behavior in windows 8.1.

                  Hi philly4,

                  Please reply with the current BIOS version of your NUC. It is very important to install the latest Chipset and Me driver.

                    I am running BIOS 0348.  The issue is fixed now after doing another clean install of Windows 10.  The only thing I did differently when I reinstalled Windows 10 the second time is that I didn't allow the computer to connect to the internet to allow any automatic updates until after I had installed the chipset drivers and ME driver.  When I had the issue, Windows 10 had already automatically installed some updates including the graphics driver and audio driver before I had a chance to install the chipset and ME drivers because I was online.
