USB Not Detected? That’s an Interview Classic

When a USB device isn’t recognized, interviewers use this scenario to test your real-world troubleshooting skills.

Why This Problem Matters

USB failures affect keyboards, mice, storage drives, and more so quick diagnosis is critical in IT support roles.

Step 1️⃣ Check the Basics First

Try a different USB port and test the device on another computer. This helps identify whether the issue is the device or the system.

Step 2️⃣ Restart the Computer

A restart can reload drivers and fix temporary glitches that stop USB devices from being recognized.

Step 3️⃣ Check Device Manager

Look for warning symbols under USB controllers. Update or reinstall drivers if a device shows an error.

Step 4️⃣ Disable USB Power Saving

Windows may turn off USB ports to save power. Adjust power settings to prevent ports from being disabled automatically.

Step 5️⃣ Update Windows

System updates can fix compatibility issues between hardware and drivers that cause USB detection failures.

Common Mistake to Avoid

Don’t assume the USB device is broken immediately. Always rule out software and driver issues first.

Interview Pro Tip

Explain your process clearly: test hardware, check drivers, adjust settings, then confirm the fix worked.
