Test a known-working device in the port and test the original device on another port before changing software.
Step by Step
- Check power, cables, wireless connection, and any physical switches or indicators first.
- Test a known-working device in the port and test the original device on another port before changing software.
- Test the device again before making additional changes.
- 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.
