Variables

bAlternateSetting ubyte bAlternateSetting;: Value used to select this alternate setting for this interface
bDescriptorType ubyte bDescriptorType;: Descriptor type. Will have value * \ref libusb_descriptor_type::LIBUSB_DT_INTERFACE LIBUSB_DT_INTERFACE * in this context.
bInterfaceClass ubyte bInterfaceClass;: USB-IF class code for this interface. See \ref libusb_class_code.
bInterfaceNumber ubyte bInterfaceNumber;: Number of this interface
bInterfaceProtocol ubyte bInterfaceProtocol;: USB-IF protocol code for this interface, qualified by the * bInterfaceClass and bInterfaceSubClass values
bInterfaceSubClass ubyte bInterfaceSubClass;: USB-IF subclass code for this interface, qualified by the * bInterfaceClass value
bLength ubyte bLength;: Size of this descriptor (in bytes)
bNumEndpoints ubyte bNumEndpoints;: Number of endpoints used by this interface (excluding the control * endpoint).
endpoint libusb_endpoint_descriptor* endpoint;: Array of endpoint descriptors. This length of this array is determined * by the bNumEndpoints field.
extra char* extra;: Extra descriptors. If libusbx encounters unknown interface descriptors, * it will store them here, should you wish to parse them.
extra_length int extra_length;: Length of the extra descriptors, in bytes.
iInterface ubyte iInterface;: Index of string descriptor describing this interface
