I am trying to recover data on my broken samsung S10 that has a jet black screen. After much research, the best route was USB to HDMI. I have successfully mirrored my phone onto my Hisense 4K Smart TV. However, devices plugged in such as mouse and keyboard are not working. The TV has two USB slots, I have tried them both. The keyboard and mouse light up so the TV has detected them. But there is no movement on screen when trying to use them. All I need to do is navigate to the settings app to sort out debugging so I am able to transfer files onto my PC. This is becoming increasingly frustrating. Is it a case that only wireless usb devices work?
You can't use a keyboard/mouse that is plugged into your TV in this case. Remember, you are mirroring your phone to the TV screen. You actually have to use a Bluetooth keyboard or keyboard/mouse combo on your phone.
