1 Check Connection

Ensure that the USB device is properly connected to the port. It sounds simple, but sometimes the device may not be fully plugged in, or there could be debris obstructing the connection. Inspect the port for any physical damage or foreign objects. Try connecting the device to a different USB port on your computer. If the device works in another port, the original port may be faulty. Additionally, try using a different USB cable if one is available, as cables can also fail.

Inspect the USB cable for any visible damage or defects. Ensure that the USB cable is securely connected to both the device and the USB port on your computer. Try unplugging and reconnecting the USB cable. Test the device with a different USB cable to rule out a faulty cable. Check if the USB port is physically damaged or obstructed by debris. Try connecting the device to a different USB port on your computer.

2 Restart System

A classic troubleshooting step is to restart your computer. This can resolve a host of issues, including those related to USB ports. When you restart, the system refreshes its software connections and can often recognize devices that were previously undetected. Before restarting, safely eject any connected USB devices to prevent data loss. After rebooting, try connecting your USB device again to see if the issue has been resolved.

Save any open work and close all running applications. Restart your computer by selecting "Restart" from the Start menu or by pressing the power button. After the computer restarts, reconnect the USB device and check if it is detected. Restarting the system can often resolve temporary glitches or issues with USB port detection.

3 Update Drivers

USB ports rely on software drivers to function correctly. These drivers can become outdated or corrupted, leading to connectivity issues. To update them, access the Device Manager on your computer—usually found in the Control Panel—and look for the USB controllers section. Right-click on the USB drivers and select "Update Driver Software." Follow the prompts to let your system search for and install any available driver updates.

Open the Device Manager (search for "Device Manager" in the Start menu or search bar). Locate the USB device or USB host controller in the list of devices. Right-click on the device and select "Update driver" or "Update driver software." Choose the option to automatically search for updated driver software online. Install any available driver updates and restart your computer if prompted. Outdated or corrupt drivers can prevent USB devices from being detected properly.

4 Disable Power Saving

Your computer's power saving settings can sometimes turn off USB ports to save energy. To check this, go to the Power Options in the Control Panel. Look for 'USB settings' and then 'USB selective suspend setting.' If it is enabled, disable it and see if your device is now detected. This setting can be particularly problematic for devices that require a constant power supply to function properly.

Open the Control Panel and navigate to "Power Options" or "Power Settings." Click on "Change plan settings" for the currently selected power plan. Click on "Change advanced power settings." Locate the "USB settings" or "USB selective suspend settings" option. Expand the option and disable or uncheck the setting that allows the USB ports to be turned off to save power. Click "Apply" and "OK" to save the changes. Power-saving features can sometimes cause USB ports to become unresponsive or stop detecting devices.

5 Reset USB Ports

Sometimes, resetting the USB ports can resolve detection issues. To do this, open Device Manager and expand the 'Universal Serial Bus controllers' section. Uninstall each USB port by right-clicking and selecting 'Uninstall.' Don't worry—upon restarting your computer, the system will automatically reinstall the drivers for these ports. After rebooting, check if your USB devices are recognized.

6 Check BIOS/UEFI

The BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) settings on your computer may have options that affect USB port functionality. To access these settings, you'll need to restart your computer and press a specific key (often F2, F10, DEL, or ESC) during startup. Once in the BIOS/UEFI menu, look for settings related to USB ports and ensure they are enabled. Save any changes and exit to reboot your system.
