After updating to Calibre 3.12, the system (windows 7 pro) has been restarted with my Kindle connected in a usb port. At the restart Windows has installed a driver for my Kindle device and Calibre no more recognize it. Now the Kindle name is "Kindle Internal Storage SCSI Disk Device" instead "Amazon Kindle". Any idea on what's happened? (The device is connected and readible with explorer)
