Historically DH takes pictures with his phone, plugs his phone USB connector to the computer. The computer opens File Explorer, reflects his phone in the Quick Access links on the left side. He views his pictures and then can copy them to his computer. Since yesterday, the computer does not recognize his phone as a connected device. Nothing has changed in the process or in the hardware (laptop, phone, USB cable.) His phone charges fine when cabled to the laptop but other than that, the computer doesn't appear to recognize the phone. The laptop has a USB 'plug' for a wireless mouse which is working fine. I took that out and used that USB port to plug in his phone USB cable - nothing. I moved the wireless mouse 'plug' to all the other USB ports - and it works everywhere, so I don't think it's a problem with the ports. I then plugged my Phone/Cable into his laptop USB port. My phone charges, but the laptop doesn't recognize my phone/cable combination as a device either. Not sure what to try next and looking for ideas?
