Fixing computers problems by just switching USB ports

IfIf If you experience problems with a USB-connected peripheral, try switching the USB port. I’ve observed this with a camera and a printer on different computers. Just switching the port I plugged the cable into fixed the problem. Just like that. 

Why this occurs, I am not sure. The USB hardware must connect and a software “handshake” must take place. If one port doesn’t work, try another. Save yourself a service call.
