Input event interface devices not found in expected location /dev/input/eventX

I went through the installation steps as normal, but after running `../configure` I got this message:

configure: error: Input event interface devices not found in expected location /dev/input/eventX !
```
I am running this in the Chrome Terminal.

Start with the ../configure entry point and the check for /dev/input/eventX shown in the issue. Reproduce the configure command in the reported Chrome Terminal environment and determine why the expected input-event devices are not found. Done means the environment-specific failure is explained and the issue's configure behavior or documentation is updated accordingly.
