Data Fields | |
uint8_t | bLength |
Size of this descriptor (in bytes) | |
uint8_t | bDescriptorType |
Descriptor type. More... | |
uint8_t | bFirstInterface |
Interface number of the first interface that is associated with this function. | |
uint8_t | bInterfaceCount |
Number of contiguous interfaces that are associated with this function. | |
uint8_t | bFunctionClass |
USB-IF class code for this function. More... | |
uint8_t | bFunctionSubClass |
USB-IF subclass code for this function. More... | |
uint8_t | bFunctionProtocol |

uint8_t | iFunction |
Index of string descriptor describing this function. | |
A structure representing the standard USB interface association descriptor.
This descriptor is documented in section 9.6.4 of the USB 3.0 specification. All multiple-byte fields are represented in host-endian format.
uint8_t libusb_interface_association_descriptor::bDescriptorType |
Descriptor type.
Will have value libusb_descriptor_type::LIBUSB_DT_INTERFACE_ASSOCIATION LIBUSB_DT_INTERFACE_ASSOCIATION in this context.
uint8_t libusb_interface_association_descriptor::bFunctionClass |
USB-IF class code for this function.
A value of zero is not allowed in this descriptor. If this field is 0xff, the function class is vendor-specific. All other values are reserved for assignment by the USB-IF.
uint8_t libusb_interface_association_descriptor::bFunctionSubClass |
USB-IF subclass code for this function.
If this field is not set to 0xff, all values are reserved for assignment by the USB-IF
uint8_t libusb_interface_association_descriptor::bFunctionProtocol |
USB-IF protocol code for this function.
These codes are qualified by the values of the bFunctionClass and bFunctionSubClass fields.
