What is a USB device and how to use it?

A USB device refers to any peripheral device that plugs into the computer via a USB port. Today, there are many different USB devices that can be connected to your computer, anything from USB flash drives and external hard drives, to keyboards and mice. They are essential to function your everyday computer applications and to store important data. External hard drives and flash drives are common USB devices. These USB storage devices are so cheap, fast and lightweight that you can easily back up important data and transfer data between different computers.

How to use a USB device? Generally, it's easy as a pie for everyone to connect a USB device to the laptop. There is no need to turn off the laptop, run a special program or wave a magic wand. Just plug the USB device into your laptop and it will be recognized at once. A USB flash drive, for example, may appear instantly in the My Computer window, ready for access.

Annoying as it seems, it's still possible to fix the USB device not recognized/working error. The following part provides 11 effective solutions that can help you fix this error.

Solution 1: Try a different USB port

First and foremost, you should make sure whether the USB port is working or not. You can disconnect the USB device which cannot be recognized by your Windows and then reconnect it via a different USB port. If you are using a desktop, you can try connecting the USB device to your computer via the USB port on the back of the case instead of the front.
