Data Fields | |
uint8_t | bLength |
Size of this descriptor (in bytes) | |
uint8_t | bDescriptorType |
Descriptor type. More... | |
uint8_t | bInterfaceNumber |
Number of this interface. | |
uint8_t | bAlternateSetting |
Value used to select this alternate setting for this interface. | |
uint8_t | bNumEndpoints |
Number of endpoints used by this interface (excluding the control endpoint). | |
uint8_t | bInterfaceClass |
USB-IF class code for this interface. More... | |
uint8_t | bInterfaceSubClass |
USB-IF subclass code for this interface, qualified by the bInterfaceClass value. | |
uint8_t | bInterfaceProtocol |
USB-IF protocol code for this interface, qualified by the bInterfaceClass and bInterfaceSubClass values. | |
uint8_t | iInterface |
Index of string descriptor describing this interface. | |
const struct libusb_endpoint_descriptor * | endpoint |
Array of endpoint descriptors. More... | |
const unsigned char * | extra |

A structure representing the standard USB interface descriptor.
This descriptor is documented in section 9.6.5 of the USB 3.0 specification. All multiple-byte fields are represented in host-endian format.
uint8_t libusb_interface_descriptor::bDescriptorType |
Descriptor type.
Will have value libusb_descriptor_type::LIBUSB_DT_INTERFACE LIBUSB_DT_INTERFACE in this context.
uint8_t libusb_interface_descriptor::bInterfaceClass |
USB-IF class code for this interface.
See libusb_class_code.
const struct libusb_endpoint_descriptor* libusb_interface_descriptor::endpoint |
Array of endpoint descriptors.
This length of this array is determined by the bNumEndpoints field.
const unsigned char* libusb_interface_descriptor::extra |
Extra descriptors.
If libusb encounters unknown interface descriptors, it will store them here, should you wish to parse them.
int libusb_interface_descriptor::extra_length |
Length of the extra descriptors, in bytes.
Must be non-negative.
