Common Class Definitions

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

#include <CDCClassCommon.h>

Data Fields

USB_Descriptor_Header_t Header
 
uint8_t MasterInterfaceNumber
 
uint8_t SlaveInterfaceNumber
 
uint8_t Subtype
 

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.

Field Documentation

USB_Descriptor_Header_t USB_CDC_Descriptor_FunctionalUnion_t::Header
