I've build simple buildroot rootfs (2012.08 based) with QT4.8.2, my small qt application and dropbear. I can start my application and it is working fine. When need to add keyboard handling from USB keyboard application hang (with no useful data in console) that way: export QWS_KEYBOARD="LinuxInput:/dev/input/event0" ./app -qws I've double check qt configuration and linuxinput is checked. Anybody have same troubles? Thanks.

I remember having problems with Qt as soon as I started defining QWS_KEYBOARD, but I don't remember if the problem was exactly the one you had. Can you try to add the attached patch to the Qt package? It has been written for Qt 4.7.3, but since the patch is trivial, I guess it can be quickly adapted to Qt 4.8.2. It's the patch I had to fix the problem I encountered, but again I don't remember the exact problem, and I have been apparently too lazy to describe it in the patch description.

It helps. It's not freezing with your patch. Great. The patch is more a workaround than a real bug, but it would be nice to implement a real fix and submit it upstream.
