exporting QWS_KEYBOARD=LinuxInput:/dev/input/event0" hang application

[binaural]

Hi,

I'm trying to use usb keyboard for my qt application so I plug keyboard check hexdump /dev/input/event0
if getting events and define export QWS_KEYBOARD="LinuxInput:/dev/input/event0".
When I run any application it hang (also qt demo). I've double check if I have linuxinput support compiled
and it is. Any ideas what could cause such behavior?

qt4.8.2 - details : http://www.qtcentre.org/threads/50999-Moving-widget-to-second-screen-not-working
Thanks.

Update: there was an issue in qkbdlinuxinput_qws.cpp.
I just comment this part and it start working. This is just workaround
not solution but when have time will look and post proper patch upstream.
Cheers.
