When Calibre is already open and a device is then connected via USB, Calibre sometimes fails to detect it. Currently the only workaround is to close and reopen Calibre entirely. A "Rescan for devices" button (or menu option under Device menu) would trigger the same device polling that happens at startup, allowing users to force detection without restarting. This is especially useful for USB devices connected after launch.
