USB device not recognised? The Device Manager pass

A keyboard, mouse or drive that Windows ignores is usually a port, cable, or driver state — not the device itself. Work through the path before you buy anything.

What that means

Medium risk. This fix changes system settings, services, drivers, startup items or security features — reversible, but taking it back takes some effort or knowledge, and it may temporarily affect stability. This change is reversible — you can return to the previous state without professional help or data loss.

USB troubleshooting in order — a different port, cable and no hub first, then power-cycling with the device unplugged, Device Manager update or uninstall-and-reboot, and USB selective suspend off

Steps

How to verify the fix

The device appears in Device Manager without warnings and does its job — keyboard types, mouse moves, or the drive shows up in File Explorer with files readable.

If this didn't fix it

Still missing or erroring after port, cable and driver checks — test it on another PC; if it works there the fault is this machine's USB controller, not the device.
