Do you also have the debug lib from Qt on your target ?

I wan't in town yesterday so I couldn't test that yesterday - sorry for that
I'm sorry but I can't find the debug lib...I crosscompild my Qt again and added the option - debug... but no debug lib was created- and also with the libs I compiled with the debug options, the QT_DEBUG_PLUGINS dosn't work
BTW I also set the PluginPath with QT_PLUGIN_PATH=... but that wasn't successful neither.
Also included: qDebug()<<QLibraryInfo::location(QLibraryInfo::PluginsPath);
It shows the correct Path("/usr/local/Trolltech/QtEmbedded-4.8.4-arm/plugins"
), where the plugin is installed... -
Did you do a clean build ?

Yes I did...
-
Just to be on the safe side, did you check the output of the configure script to see if it was a debug or release build ?

If i checked the right file ist says DEBUG=auto, however the libs I compiled with the debug options are pretty big so I think they are build during debug build
-
so if you call
@QT_DEBUG_PLUGINS=1 ./myApplication -qws@
You don't have any output ?

It's getting strange...
What do you mean by "because of the USB" ? What do you have exactly there ?
