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.

Note:

Regardless of CPU architecture, these values should be stored as little endian.
