■
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.
