When something "stops working," start at the connection—not the expensive part.
1. Unplug and firmly reseat the cable at both ends (device and wall/dock/router).
2. Try a known-good cable of the same type before you replace hardware.
3. Test that cable on a second device or port so you know which side failed.
4. Only then move on to drivers, settings, or buying a replacement.
What's the last time a "broken" gadget was really just a loose or tired cable?
