How to Fix USB Port Not Working in Windows 11

USB ports are essential for connecting external devices such as flash drives, keyboards, mice, printers, and external hard drives to your Windows 11 PC. When a USB port stops working, connected devices may not be detected, fail to receive power, or show error messages such as “USB device not recognized.” This can disrupt productivity and prevent access to important peripherals.

USB port not working in Windows 11 is typically caused by outdated or corrupted drivers, power management settings, hardware issues, disabled USB controllers, Windows update conflicts, or system file corruption. Since USB functionality depends on both hardware and software components, resolving the issue requires a structured troubleshooting approach.

This guide explains how to fix USB port not working in Windows 11 step by step.
