Data Fields

uint8_t bFunctionLength
uint8_t bDescriptorType
uint8_t bDescriptorSubType
uint8_t bMasterInterface
uint8_t bSlaveInterface0

Detailed Description

Type define for a CDC class-specific functional Union descriptor. This indicates to the host that specific CDC control and data interfaces are related. See the CDC class specification for more details.

See also:
USB_CDC_Descriptor_FunctionalUnion_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.

Type of the descriptor, either a value in USB_DescriptorTypes_t or a value given by the specific class.

Size of the descriptor, in bytes.

Interface number of the CDC Control interface.
