Does closing & re-opening the folder tree, or the whole window, refresh the name? If so, a button/hotkey can be made which does that, and avoids restarting the whole program or affecting other windows.
Another thing to check is that you have not launched dopus.exe elevated via UAC. If you do that then Windows will block the change notifications about the device from reaching Opus. You can use Opus's built-in UAC support and Admin-Mode functionality to elevate individual windows or actions, but the dopus.exe process itself needs to be run at the same level as the desktop/taskbar/etc. in order for them to talk to it. See here for more info.
