Summary

USB device Audio Maximum Number of instances

This macro defines the number of instances of the Audio Function Driver. For example, if the application needs to implement two instances of the Audio Function Driver (to create two composite Audio Device) on one USB Device, the macro should be set to 2. Note that implementing a USB Device that features multiple Audio interfaces requires appropriate USB configuration descriptors.
