Windows 10: Device Manager: USB and Unknown device problem

Hello, I recently encountered a problem in device manager where a device was missing a driver and a USB Device malfunctioned. I am not really sure what caused this to happen because I just reinstalled Windows a week ago

Here is the name of my device if needed: HP ENVY dv7-7243nr Notebook PC


Here are some screenshots of device manager:



Here is the info for the unknown device:






Here are the screenshots for the USB device:

X800 GTO2 = Unknown Device

I flashed the BIOS on my X800 GTO2 last night and it is listed in the Device Manager as an Unknown Device. Is this normal?

 

Usb not recognized(unknown device) problem

As above! No usb drive/flash disk,keyboard,mouse on usb ports etc etc but still popping in, on and off tried to new Windows. Tried all solutions on internet but still no joy. Device manager showing unknown device. Motherboard Asus x99 sabertooth. update bios from old to new. no luck

 

Unknown device problem

I ran the INF update utility and it appeared to complete normally. I rebooted, but still had the unknown device error, so I tried running the management engine device update again and it hung at creating process UNS.exe - I let it run 2 hours and device manager indicated CPU usage was 25% (the processor is 4 core), so it looked like it hung in a loop.

It seems to me that I had this problem with an earlier machine with a different motherboard and a core 2 duo processor.

I thank you for your help, but I guess I will just live with it. As far as I can tell, the unknown device is not creating a problem. I just wish I knew what it is.
