Variables

MaxPower ubyte 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.
bConfigurationValue ubyte bConfigurationValue;: Identifier value for this configuration
bDescriptorType ubyte bDescriptorType;: Descriptor type. Will have value * \ref libusb_descriptor_type::LIBUSB_DT_CONFIG LIBUSB_DT_CONFIG * in this context.
bLength ubyte bLength;: Size of this descriptor (in bytes)
bNumInterfaces ubyte bNumInterfaces;: Number of interfaces supported by this configuration
bmAttributes ubyte bmAttributes;: Configuration characteristics
extra char* extra;: Extra descriptors. If libusbx encounters unknown configuration * descriptors, it will store them here, should you wish to parse them.
extra_length int extra_length;: Length of the extra descriptors, in bytes.
iConfiguration ubyte iConfiguration;: Index of string descriptor describing this configuration
iface libusb_interface* iface;: Array of interfaces supported by this configuration. The length of * this array is determined by the bNumInterfaces field.
wTotalLength ushort wTotalLength;: Total length of data returned for this configuration
