| const struct libusb_interface * | interface |
| const unsigned char * | extra |
| int | extra_length |
A structure representing the standard USB configuration descriptor. This descriptor is documented in section 9.6.3 of the USB 2.0 specification. All multiple-byte fields are represented in host-endian format.
| uint8_t libusb_config_descriptor::bConfigurationValue |
Identifier value for this configuration
| uint8_t libusb_config_descriptor::bDescriptorType |
Descriptor type. Will have value libusb_descriptor_type::LIBUSB_DT_CONFIG LIBUSB_DT_CONFIG in this context.
| uint8_t libusb_config_descriptor::bLength |
Size of this descriptor (in bytes)
| uint8_t libusb_config_descriptor::bmAttributes |
Configuration characteristics
| uint8_t libusb_config_descriptor::bNumInterfaces |
Number of interfaces supported by this configuration
| const unsigned char* libusb_config_descriptor::extra |
Extra descriptors. If libusb encounters unknown configuration descriptors, it will store them here, should you wish to parse them.
| int libusb_config_descriptor::extra_length |
Length of the extra descriptors, in bytes.
| uint8_t libusb_config_descriptor::iConfiguration |
Index of string descriptor describing this configuration
| const struct libusb_interface* libusb_config_descriptor::interface |
Array of interfaces supported by this configuration. The length of this array is determined by the bNumInterfaces field.
| uint8_t libusb_config_descriptor::MaxPower |
Maximum power consumption of the USB device from this bus in this configuration when the device is fully opreation. Expressed in units of 2 mA.
| uint16_t libusb_config_descriptor::wTotalLength |
Total length of data returned for this configuration
