Sometimes users, when trying to connect and continue using USB devices (flash drives, external hard drives), get a system error that says that this USB device is not recognized. Why such a reaction to the device occurs, it’s hard to say for sure. Let's try to figure out what is the reason for this behavior of the operating system and how to fix connection errors.
The USB device is not recognized. Why is there such a failure?
To begin with, not a single Windows-system is immune from the appearance of short-term failures, which can lead to such situations.

As for the rest, as it was already possible to notice, the proposed solutions to fix such failures are quite simple and they are mainly associated exclusively with drivers. Therefore, as a first step, you can just upgrade them or reinstall them (you can even remove devices from the system so that when you restart it, it installs the drivers on its own).
