#include <libusb.h>
Data Fields | |
uint8_t | bLength |
Size of this descriptor (in bytes) | |
uint8_t | bDescriptorType |
Descriptor type. | |
uint8_t | bEndpointAddress |
The address of the endpoint described by this descriptor. | |
uint8_t | bmAttributes |
Attributes which apply to the endpoint when it is configured using the bConfigurationValue. | |
uint16_t | wMaxPacketSize |
Maximum packet size this endpoint is capable of sending/receiving. | |
uint8_t | bInterval |
Interval for polling endpoint for data transfers. | |
uint8_t | bRefresh |
For audio devices only: the rate at which synchronization feedback is provided. | |

A structure representing the standard USB endpoint descriptor.
This descriptor is documented in section 9.6.6 of the USB 3.0 specification. All multiple-byte fields are represented in host-endian format.
uint8_t libusb_endpoint_descriptor::bDescriptorType |
Descriptor type.
Will have value libusb_descriptor_type::LIBUSB_DT_ENDPOINT LIBUSB_DT_ENDPOINT in this context.
uint8_t libusb_endpoint_descriptor::bEndpointAddress |
The address of the endpoint described by this descriptor.
Bits 0:3 are the endpoint number. Bits 4:6 are reserved. Bit 7 indicates direction, see libusb_endpoint_direction.
uint8_t libusb_endpoint_descriptor::bmAttributes |
Attributes which apply to the endpoint when it is configured using the bConfigurationValue.
Bits 0:1 determine the transfer type and correspond to libusb_transfer_type. Bits 2:3 are only used for isochronous endpoints and correspond to libusb_iso_sync_type. Bits 4:5 are also only used for isochronous endpoints and correspond to libusb_iso_usage_type. Bits 6:7 are reserved.
uint16_t libusb_endpoint_descriptor::wMaxPacketSize |
Maximum packet size this endpoint is capable of sending/receiving.
uint8_t libusb_endpoint_descriptor::bInterval |
Interval for polling endpoint for data transfers.
uint8_t libusb_endpoint_descriptor::bRefresh |
For audio devices only: the rate at which synchronization feedback is provided.
const unsigned char* libusb_endpoint_descriptor::extra |
Extra descriptors.
If libusbx encounters unknown endpoint descriptors, it will store them here, should you wish to parse them.
int libusb_endpoint_descriptor::extra_length |
Length of the extra descriptors, in bytes.
