#include <CDCClassCommon.h>

Data Fields

uint8_t bFunctionLength
uint8_t bDescriptorType
uint8_t bDescriptorSubType
uint8_t bmCapabilities

Detailed Description

Type define for a CDC class-specific functional ACM descriptor. This indicates to the host that the CDC interface supports the CDC ACM subclass of the CDC specification. See the CDC class specification for more details.

See also:
USB_CDC_Descriptor_FunctionalACM_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.

Field Documentation

Sub type value used to distinguish between CDC class-specific descriptors, must be CDC_DSUBTYPE_CSInterface_ACM.

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.

Capabilities of the ACM interface, given as a bit mask. For most devices, this should be set to a fixed value of 0x06 - for other capabilities, refer to the CDC ACM specification.
