you're receiving is sent when the device is plugged in, regardless of
whether it's mounted or not. If you plug in your USB device, and it's not
mounted you catch the signal that a device was added but since it's not
mounted filePath() will return QString().
Try this in your slot:
qDebug() << "Device changed " << str;
QString filePath;
Solid::Device device(str);
Solid::StorageAccess *accessStorage = device.as<Solid::StorageAccess>();
if(storageAccess) {
if(!storageAccess->isAccessible()) { //device is plugged in but not
mounted
storageAccess->setup();
}
qDebug() << "File path is: " << storageAccess->filePath();
}
