CDC class-specific Functional Union Descriptor (LUFA naming conventions). More...

#include <CDCClassCommon.h>

Data Fields
USB_Descriptor_Header_t	Header
uint8_t	Subtype
uint8_t	MasterInterfaceNumber
uint8_t	SlaveInterfaceNumber

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_StdDescriptor_FunctionalUnion_t for the version of this type with standard element names.

Note:

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