Sorry, don’t speak English, ONLINE TRANSLATOR. Hello. Acquired XD05 Basic, very pleased with the sound quality. But I don’t understand how to connect the device to the PC directly without using the battery for power. When connecting a cable from a “PC” to a “USB in” and “input” slot in the middle position (in the middle), everything works, but a battery is used for power supply. When connected to the “DC 5V” partition, the battery is charged, but the PC does not determine XD05 Basic, as if the device is not connected at all. Can you explain how the device should be connected without battery power?
