QFileSystemModel not updating on insertion of removable disc

[pmh4514]

Using Qt5.5.1 on Win8.1 64bit (MSVC2013), I have a QFileSystemModel attached to a QTreeView.

It works quite well to instantly reflect changes made with Windows like deleting, adding, renaming folders and files:

   QTreeView tree = new QTreeView(this);
   QFileSystemModel dirModel = new QFileSystemModel(this);  
   dirModel->setRootPath(dirModel->myComputer().toString());
   tree->setModel(dirModel);

The problem is, if I attach an external USB drive, I'd expect the file-system model to reflect the new drive. But it doesn't. What am I doing wrong?

Qt support has informed me that this is a known bug in Windows and there is no solution at this time. A workaround is to destroy and recreate the model.
