Hi,

there are two things to consider:

1. Check if there are drivers enabled in buildroot config. The default
configuration does not include any drivers. I stepped in this trap when
I started to use QT.

BTW: Shouldn't we change this to some useful default?

2. QT needs environment variables to configure input devices.

Hope this helps

Stephan
