Detailed Fixes for “USB doesn’t work in Windows 10”
Below are step-by-step explanations and fixes for each reason from the quick guide. Follow them in order — simple hardware checks first, then move into software fixes.
1. Faulty cable, device or port
Why it causes the problem:
- Physical faults (broken wires, bent pins, worn connectors) prevent data/power transfer, so the device doesn’t enumerate.
Step-by-step solution:
- Try the device on a different USB port on the same PC (front vs. rear on desktops).
- Try a different USB cable (especially for USB-C/micro-B devices) and another known-good device on the same port.
- Test the device on a different computer. If it fails everywhere, the device or cable is likely bad.
- For desktops, test using a direct internal USB header or another machine to isolate port vs. device.
Tip: For intermittent issues, wiggle the connector gently — if that causes recognition, replace the cable or avoid that port.
2. Insufficient power for device or hub
Why it causes the problem:
- High-power devices (external HDDs, optical drives) may draw more current than an unpowered hub or a single port can supply.
Step-by-step solution:
- Connect the device directly to a rear motherboard USB port (these tend to provide more stable power).
- Use a powered USB hub (one with its own AC adapter).
- For external drives, use a Y-cable or the dual-power input if provided by the manufacturer.
- If using a laptop, plug in the laptop power adapter — some laptops limit USB power on battery.
Note: If a device spins up then disconnects, power is the most likely cause.
3. Outdated, missing or corrupt drivers
Why it causes the problem:
- Windows needs the correct driver for device enumeration and function; corrupt or incompatible drivers prevent recognition.
Step-by-step solution:
- Open Device Manager: press Windows+X, choose Device Manager.
- Look under Universal Serial Bus controllers and for the device category (e.g., Disk drives, Portable Devices).
- Right-click the problematic entry and choose Update driver → Search automatically for updated driver software.
- If no update works, choose Uninstall device (check any option to remove driver software), then reboot — Windows will reinstall drivers automatically.
- For branded devices, download the driver from the manufacturer’s site and install it.
Tip: For driver rollback, right-click device → Properties → Driver tab → Roll Back Driver (if available).
4. Corrupted USB controllers
Why it causes the problem:
- If the USB controller entries are corrupted, none of the ports may function correctly.
Step-by-step solution:
- Open Device Manager → expand Universal Serial Bus controllers.
- Right-click each entry labeled USB Root Hub, Generic USB Hub, USB Host Controller and choose Uninstall device.
- Repeat for all controllers, then restart Windows — Windows will detect hardware and reinstall controllers automatically.
- After restart, check if devices are recognized.
Warning: Don’t uninstall other critical non-USB devices; focus only on USB-related entries.
5. Power Management / USB selective suspend
Why it causes the problem:
- Windows can turn off USB ports to save power; some devices don’t wake reliably after being suspended.
Step-by-step solution:
- Open Control Panel → Power Options → click Change plan settings next to your active plan → Change advanced power settings.
- Expand USB settings → USB selective suspend setting → set to Disabled for Plugged in (and On battery if you want).
- Open Device Manager → under Universal Serial Bus controllers, right-click each USB Root Hub → Properties → Power Management tab → uncheck Allow the computer to turn off this device to save power.
- Reboot and test devices.
Note: This is especially useful for external drives and audio interfaces.
6. USB disabled in BIOS/UEFI
Why it causes the problem:
- If USB ports are disabled at firmware level, Windows cannot see devices.
Step-by-step solution:
- Restart your PC and press the BIOS/UEFI key (common keys: Del, F2, F10, Esc).
- In BIOS/UEFI settings look for Integrated Peripherals, Onboard Devices, or Advanced settings.
- Ensure USB Controller, USB Ports, and Legacy USB Support are Enabled.
- Save and exit BIOS/UEFI, then test.
Tip: Some systems have security options to disable front-panel USB — check both onboard and front-panel settings.
7. Drive letter conflict (storage devices)
Why it causes the problem:
- If the drive has no letter or one that conflicts with a network drive, Windows Explorer won’t show it.
Step-by-step solution:
- Open Disk Management: press Windows+X → Disk Management.
- Locate the external drive: it may show as Offline, Unallocated, or without a drive letter.
- Right-click the partition → Change Drive Letter and Paths → Add or Change → choose a new letter not in use.
- If the disk is offline, right-click → Online. If it’s unallocated, create a new simple volume (this will erase data).
Warning: Do not format if you need to recover data; use recovery tools first.
8. Unrecognized filesystem or RAW drive
Why it causes the problem:
- Corrupted filesystem or unsupported format (e.g., macOS HFS+) may show the drive as RAW and inaccessible.
Step-by-step solution:
- In Disk Management, check if filesystem is shown as RAW.
- Try chkdsk: open Command Prompt (Admin) and run chkdsk X: /f (replace X with the drive letter).
- If chkdsk fails, use a data-recovery tool (e.g., Recuva, TestDisk, or commercial options) to recover files.
- After recovery, reformat the drive with NTFS or exFAT via Disk Management → right-click partition → Format.
Tip: Don’t format before recovering important data.
9. Windows update or driver regression
Why it causes the problem:
- A recent Windows update or driver update might introduce incompatibilities.
Step-by-step solution:
- Open Settings → Update & Security → View update history. Note any updates installed around when the issue began.
- To uninstall an update: Settings → Update & Security → Windows Update → View update history → Uninstall updates. Remove suspect updates and reboot.
- For drivers, open Device Manager, right-click device → Properties → Driver → Roll Back Driver.
- If rolling back helps, hide the offending update using the Microsoft Show/Hide Troubleshooter to prevent automatic reinstallation.
10. Antivirus or security blocking
Why it causes the problem:
- Some security suites block USB devices to prevent data leakage or malware, disabling access.
Step-by-step solution:
- Temporarily disable third-party antivirus/security software (right-click system tray icon → disable) and test the USB device.
- Check the security suite’s settings for a “device control” or “removable media” policy and allow the device.
- If in a managed environment, contact IT — group policies may block USB access.
Warning: Re-enable antivirus after testing.
11. Corrupted system files
Why it causes the problem:
- Damaged system files can break service components responsible for USB.
Step-by-step solution:
- Open Command Prompt (Admin): press Windows, type cmd, right-click Command Prompt → Run as administrator.
- Run: sfc /scannow — wait for completion; it will repair protected files.
- If issues persist run: DISM /Online /Cleanup-Image /RestoreHealth and then rerun sfc /scannow.
- Reboot and test USB functionality.
Note: These commands can take 10–30 minutes depending on system.
12. Fast Startup interfering
Why it causes the problem:
- Fast Startup can skip full hardware initialization and leave ports in an inconsistent state.
Step-by-step solution:
- Open Control Panel → Power Options → Choose what the power buttons do.
- Click Change settings that are currently unavailable, then uncheck Turn on fast startup (recommended).
- Save changes and perform a shutdown, then power on and test USB devices.
Tip: This can resolve intermittent detection issues after reboot.
13. Physical damage or loose internal connector
Why it causes the problem:
- Port pins, solder joints, or internal connectors can fail, making ports unreliable.
Step-by-step solution:
- Inspect the port for debris, bent pins, or visible damage; power off and use compressed air to clean.
- If a laptop’s port is loose, avoid using it and use another port or a USB hub.
- For desktops, open the case and ensure front-panel USB connectors are firmly attached to the motherboard.
- If internal solder joints are broken or the port is physically damaged, have a technician replace the port or use a PCIe USB expansion card for desktops.
Warning: If you’re not comfortable opening the case, seek professional repair.
Prevention & When to Seek Help
- Use high-quality cables and a powered hub for multiple high-power devices.
- Install Windows updates and manufacturer drivers regularly, but test after major updates.
- Backup critical files on removable drives; don’t rely on a single USB stick.
- Seek professional help if ports are physically damaged, intermittent after cleaning, or if internal repairs are needed.
When to contact a technician:
- Physical damage to ports or motherboard connectors.
- Repeated failures across multiple USB controllers after driver reinstallation and sfc/DISM checks.
