Sorry if this is a dumb question. I am trying to get my Pi 3 working, it is an old one and I am sure that it has been working in the past with OSMC. My laptop is running mint 19.1, I used Etcher to create the sd, which worked fine with my Pi 1. The Pi 3 boots OK from the new sd card, until it asks for input, neither the keyboard (caps lock does not change state) or mouse work. I tried a wireless mouse and can see the sender wake up, so power is available at the USB ports. Hours of web searching have not helped. Any advice will be appreciated.
I also tried the latest Raspbian image, same result.
