When you connect the device to the computer, you must also select the correct USB mode in the device: None, Charge only, MTP, PTP, and so on. Each producer calls this mode in their own way. Never connect devices in the Media mode. If the Android device is Media mode, you are not  able to create an Android backup of the device.

For successful connection of the device, you need to make sure that there is a memory card in the device, which should have at least 1 MB available space. During the logical extraction, the agent program uses the memory card for temporary files' storage, which are deleted when the reading is finished. Files that were stored in the memory card before connection are not changed or deleted. However, it is recommended that you use your own memory card and not the one that was in the examined device.
