USB_MIDI_StdDescriptor_AudioInterface_AS_t Struct Reference

MIDI class-specific Streaming Interface Descriptor (USB-IF naming conventions). More...

#include <MIDIClassCommon.h>

Data Fields

uint16_t bcdMSC
uint8_t bDescriptorSubtype
uint8_t bDescriptorType
uint8_t bLength
uint16_t wTotalLength

Detailed Description

Type define for an Audio class-specific MIDI streaming interface descriptor. This indicates to the host how MIDI the specification compliance of the device and the total length of the Audio class-specific descriptors. See the USB Audio specification for more details.

See also
USB_MIDI_Descriptor_AudioInterface_AS_t for the version of this type with non-standard LUFA specific element names.
Regardless of CPU architecture, these values should be stored as little endian.
