Detailed Description

Type define for a standard Configuration Descriptor header. This structure uses LUFA-specific element names to make each element's purpose clearer.

See also:

USB_StdDescriptor_Configuration_Header_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

uint8_t USB_Descriptor_Configuration_Header_t::ConfigAttributes

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_Descriptor_Configuration_Header_t::ConfigurationNumber

Configuration index of the current configuration.

uint8_t USB_Descriptor_Configuration_Header_t::ConfigurationStrIndex

Index of a string descriptor describing the configuration.

USB_Descriptor_Header_t USB_Descriptor_Configuration_Header_t::Header

Descriptor header, including type and size.

uint8_t USB_Descriptor_Configuration_Header_t::MaxPowerConsumption

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

uint16_t USB_Descriptor_Configuration_Header_t::TotalConfigurationSize

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

uint8_t USB_Descriptor_Configuration_Header_t::TotalInterfaces

Total number of interfaces in the configuration.
