Detailed Description
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.
Member Data Documentation
◆ bAlternateSetting
| uint8_t libusb_interface_descriptor::bAlternateSetting |
Value used to select this alternate setting for this interface
◆ bDescriptorType
| uint8_t libusb_interface_descriptor::bDescriptorType |
Descriptor type. Will have value libusb_descriptor_type::LIBUSB_DT_INTERFACE LIBUSB_DT_INTERFACE in this context.
◆ bInterfaceClass
| uint8_t libusb_interface_descriptor::bInterfaceClass |
USB-IF class code for this interface. See libusb_class_code.
◆ bInterfaceNumber
| uint8_t libusb_interface_descriptor::bInterfaceNumber |
Number of this interface
◆ bInterfaceProtocol
| uint8_t libusb_interface_descriptor::bInterfaceProtocol |
USB-IF protocol code for this interface, qualified by the bInterfaceClass and bInterfaceSubClass values
◆ bInterfaceSubClass
| uint8_t libusb_interface_descriptor::bInterfaceSubClass |
USB-IF subclass code for this interface, qualified by the bInterfaceClass value
◆ bLength
| uint8_t libusb_interface_descriptor::bLength |
Size of this descriptor (in bytes)
◆ bNumEndpoints
| uint8_t libusb_interface_descriptor::bNumEndpoints |
Number of endpoints used by this interface (excluding the control endpoint).
◆ endpoint
| const struct libusb_endpoint_descriptor* libusb_interface_descriptor::endpoint |
Array of endpoint descriptors. This length of this array is determined by the bNumEndpoints field.
◆ extra
| 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.
◆ extra_length
| int libusb_interface_descriptor::extra_length |
Length of the extra descriptors, in bytes. Must be non-negative.
◆ iInterface
| uint8_t libusb_interface_descriptor::iInterface |
Index of string descriptor describing this interface
