How to Diagnose the “USB Device Not Recognized” Error in Windows


Windows is designed to be almost universal in its support of PC accessories, particularly USB-based add-ons like external hard drives, flash drives, game controllers, webcams, microphones, and other peripherals.

If the installed drivers or ones downloaded from the manufacturer’s site on the web aren’t working, you’ll need to manually select the device and driver using Device Manager.
