1 Initial Checks

Before diving into more complex troubleshooting, it's important to perform some initial checks. Ensure that the USB device you're trying to use is not at fault by connecting it to another computer. If it works elsewhere, the issue likely lies with your USB port or computer. Check if the USB port is physically damaged; debris or bent pins can prevent proper contact. Also, restart your computer as it can resolve temporary glitches that might be causing the power issue.

2 Power Settings

Your computer's power settings can affect how USB ports function. On Windows, you can access Device Manager, navigate to Universal Serial Bus controllers, and check the properties of USB Root Hub. Here, ensure that the option "Allow the computer to turn off this device to save power" is unchecked. This setting can sometimes disable USB ports to save energy, leading to power issues with connected devices.

3 Driver Updates

Outdated or corrupted drivers can cause USB power problems. To update them, open Device Manager, find Universal Serial Bus controllers, and right-click on each USB Root Hub and select "Update driver." Choose "Search automatically for updated driver software" and follow the prompts. If new drivers are found, they will be installed automatically, which may resolve your power issues.

4 BIOS Settings

Sometimes, USB power issues can be resolved by tweaking settings in the BIOS (Basic Input/Output System). Restart your computer and enter the BIOS setup (usually by pressing a key like F2, Delete, or Esc during startup). Look for settings related to USB ports, such as "USB Legacy Support," and ensure they are enabled. Be cautious when changing BIOS settings; incorrect configurations can cause other issues.

5 External Hubs

If you're using an external USB hub that consolidates multiple USB devices into one port, ensure that it's a powered hub, especially if you're connecting high-power devices like external hard drives. Unpowered hubs may not provide sufficient power to all connected devices, leading to recognition and functionality issues. Connecting the hub to its own power source can resolve these problems.

6 Advanced Solutions

For persistent USB power issues, advanced solutions may be necessary. This could involve editing the system registry on Windows or running terminal commands on macOS or Linux. For example, on Windows, you can use the powercfg command to generate a report on power settings that might affect USB ports. Note that these methods require a higher level of computer knowledge and should be approached with caution.
