1 Check Ports

Firstly, check the USB ports on your computer. Sometimes, the problem is as simple as a dusty or physically damaged port. Gently clean the port with compressed air and try connecting the USB device to a different port. If the device works on another port, the original port may be defective. It's also wise to check if the device works on another computer, which can help determine if the issue lies with the USB device itself or your computer.

Ensure that the USB device is properly connected to a functional USB port on your computer. Try connecting the device to different USB ports to rule out port-related issues.

Verificar se o dispositivo USB apresenta alguma deficiência visual/mecanica, caso n?o apresente experimentar o dispositivo em outro computador, caso funcione, definitivamente o problema está na porta do computador.

2 Restart PC

A classic fix for many technical issues is restarting your computer. This can resolve temporary glitches in the system that might be causing the USB device not to be recognized. Close all your active programs, initiate a proper shutdown, and then start your computer again. Once rebooted, try connecting the USB device once more to see if it is recognized.

3 Update Drivers

USB devices require drivers, which are software components that allow the operating system to communicate with hardware devices. If these drivers are outdated or corrupted, your USB device may not be recognized. Access your computer's Device Manager, locate the USB device (which may be listed as an 'Unknown Device' if not recognized), and update the driver software. If an update is available, install it and check if the problem is resolved.

Check if the USB device requires specific drivers to function properly. Visit the manufacturer's website to download and install the latest drivers for the device. Updating drivers can resolve compatibility issues and improve recognition.

4 Change Settings

Power settings in Windows can turn off USB ports to save energy, leading to recognition issues. To adjust this, go into your computer's Power Options and disable the setting that allows the computer to turn off USB devices to save power. Additionally, check your computer's BIOS (Basic Input/Output System) settings to ensure that USB ports are enabled. The BIOS is a firmware interface that initializes hardware during the startup process.

5 Scan for Hardware

Sometimes, your operating system might not automatically detect new hardware. Manually scanning for hardware changes can prompt it to recognize the USB device. Open Device Manager, select 'Action', and then 'Scan for hardware changes'. This can force your computer to recognize any connected USB devices that it previously overlooked.

6 Troubleshoot Errors

If all else fails, use the built-in troubleshooting tools provided by your operating system. Windows, for instance, has a 'Hardware and Devices' troubleshooter that can find and fix problems with devices and hardware. You can access this tool through the Control Panel. Follow the prompts to diagnose and resolve issues related to your USB device not being recognized.
