Detailed Description

Type define for a standard Configuration Descriptor header. This structure uses the relevant standard's given element names to ensure compatibility with the standard.

See also:

USB_Descriptor_Device_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.

Field Documentation

uint8_t USB_StdDescriptor_Configuration_Header_t::bConfigurationValue

Configuration index of the current configuration.

uint8_t USB_StdDescriptor_Configuration_Header_t::bDescriptorType

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

uint8_t USB_StdDescriptor_Configuration_Header_t::bLength

Size of the descriptor, in bytes.

uint8_t USB_StdDescriptor_Configuration_Header_t::bmAttributes

Configuration attributes, comprised of a mask of USB_CONFIG_ATTR_* masks. On all devices, this should include USB_CONFIG_ATTR_RESERVED at a minimum.

uint8_t USB_StdDescriptor_Configuration_Header_t::bMaxPower

Maximum power consumption of the device while in the current configuration, calculated by the USB_CONFIG_POWER_MA() macro.

uint8_t USB_StdDescriptor_Configuration_Header_t::bNumInterfaces

Total number of interfaces in the configuration.

uint8_t USB_StdDescriptor_Configuration_Header_t::iConfiguration

Index of a string descriptor describing the configuration.

uint16_t USB_StdDescriptor_Configuration_Header_t::wTotalLength

Size of the configuration descriptor header, and all sub descriptors inside the configuration.
