What to Do When Windows Says USB Device Not Recognized

Troubleshoot a USB drive, printer, camera, or accessory Windows cannot identify.

Quick Answer

Disconnect and reconnect it, try another USB port/cable, restart Windows, then check Device Manager.

Step by Step

  1. Check power, cables, wireless connection, and any physical switches or indicators first.
  2. Disconnect and reconnect it, try another USB port/cable, restart Windows, then check Device Manager.
  3. Test the device again before making additional changes.
  4. If the problem remains, check Windows Settings and Device Manager, then use the manufacturer's official support information for the exact model.

If That Doesn't Work

  • Change one thing at a time so you know which action fixed or caused the problem.
  • Avoid downloading drivers or device utilities from unofficial driver-download websites.
