USB port malfunction

I have a Dell XPS 15Z. I have a problem with my computer sometimes not recognizing what's plugged into my USB ports. This occurs with my external drives and my printer.
Sometimes I can turn the computer off and on and then they will be recognized, but not always. I cannot find a pattern to when it works and when it doesn't.
Is this a hardware or software problem? Any advice
would be appreciated. Many thanks.
