Some QPA plugins, like LinuxFB, don't load their own input handlers, so you need to do this yourself by passing additional -plugin arguments when you start your app. These are called "generic" plugins and can be found in qtbase/src/plugins/generic. For example:

./myapp -platform linuxfb -plugin EvdevMouse -plugin EvdevKeyboard

Those plugins will automatically try to open the first mouse/keyboard in /dev/input. Make sure the user has read permissions for those devices (you should see warning messages if opening fails). For specifying additional parameters that get passed to the plugin(s), please consult each individual plugin's source code.
