// Abstraction which provides the platform specific USB Audio Host class
// implementation: USBAudioHostStream reads from an attached USB microphone
// and/or writes to an attached USB speaker with the same API as the
// USBAudioStream device.
//
// - Adafruit TinyUSB (USE_TINYUSB / USE_TINYUSB_HOST: RP2040/RP2350, SAMD,
//   nRF52, CH32 with a native host port, Pico-PIO-USB or MAX3421E):
//   USBAudioHostTinyUSB, or USBAudioHostTinyUSBFreeRTOS with USE_FREERTOS
// - ESP32-S2/S3/P4: USBAudioHostESP32 using the ESP-IDF usb_host library.
//   Define USE_TINYUSB before including this file to use the Adafruit
//   TinyUSB host stack instead.
// - STM32: USBAudioHostTinyUSB (Adafruit TinyUSB with host support)
