Fix USB Device Connection Issues
When Windows doesn't recognize your USB drive, external hard drive, or other USB device.
Basic Troubleshooting
- Unplug and replug - Remove the device, wait 10 seconds, plug it back in
- Try a different USB port - Use a port directly on the computer, not a hub
- Try the USB 2.0 ports - Usually the black ports; sometimes more compatible
- Restart your computer with the device unplugged, then plug it in after restart
If Using a USB Hub
- Connect the device directly to your computer instead
- If hub is essential, try a powered hub (one with its own power adapter)
- Don't overload hubs with too many devices
For USB Flash Drives
- Try the drive in another computer to test if it works
- Check if the drive appears in File Explorer
- Open Disk Management (right-click Start button) to see if it shows there
- If visible in Disk Management but not File Explorer, it may need a drive letter assigned
For External Hard Drives
- Ensure the drive has external power if required
- Listen for the drive spinning up
- Try a different USB cable
- Check Disk Management to see if it's recognized but not mounted
Update USB Drivers
- Right-click the Start button
- Select Device Manager
- Expand Universal Serial Bus controllers
- Right-click each item and select Update driver
- Choose Search automatically for drivers
