„ Descriptor Overview
When the device is connected to USB bus, the host assigns specific address to the device. Then the host reads the device
information, which is called as descriptor, through default pipe (Endpoint 0). The AK5371A consists of one Device Descriptor, one
Configuration Descriptor, two Interface Descriptors, and two Endpoint Descriptors.
Figure 6 shows Descriptor’s hierarchy.
