RE: Win10 - Device Unknown (Inspiron 5748)

Read this, "How to reinstall drivers in the correct order"

* Go to the File Library for your system model
* Change the operating system to Windows 10 if it is not already chosen
* Open Chipset
* Install each one, one at a time, restarting the laptop after each one
* Check the Device Manager to see if there are anymore unknown devices

RE: Win10 - Device Unknown (Inspiron 5748)

Sorry, DELL-Chris M. No such luck.

I tried what you suggested

After that failed, I let Dell's "Detect Drivers" app tell me what drivers were missing & tried to install them. Some (that were already installed) were successful but several failed, saying "Not correct for this laptop". Then, I downloaded ALL of the drivers for the Inspiron 5748 laptop & tried to install them, one by one. Again, those that were for hardware installed in my laptop were successful & the rest were not.

Through all of this, I still have the same three "Unknown" devices.

Any other ideas?
