[Qt-interest] QFile.waitForReadyRead() not working on dev file

[Linus Casassa]

Hi

waitForReadyRead() always returns 0 without waiting 1 second. It prints
thousands of "looping"s.

The reading works grate if I take waitForReadyRead() out but it gets blocked
until data arrives so I can't do other things in the meanwhile..

QFile device("/dev/input/js0");
if ( !device.open( QIODevice::ReadOnly ) )
{
    qWarning( "Failed opening device." );
    return FALSE;
}

while(1) {
    if ( device.waitForReadyRead(1000))
        if ( device.read( (char*)&data, data_sz ) == data_sz )
            ...
    qWarning("looping");
}

Thank you very much in advance.
