Detailed Description

A structure representing the standard USB device descriptor.

This descriptor is documented in section 9.6.1 of the USB 3.0 specification. All multiple-byte fields are represented in host-endian format.

Field Documentation

uint8_t libusb_device_descriptor::bDescriptorType

Descriptor type.

Will have value libusb_descriptor_type::LIBUSB_DT_DEVICE LIBUSB_DT_DEVICE in this context.

uint16_t libusb_device_descriptor::bcdUSB

USB specification release number in binary-coded decimal.

A value of 0x0200 indicates USB 2.0, 0x0110 indicates USB 1.1, etc.

uint8_t libusb_device_descriptor::bDeviceClass

USB-IF class code for the device.
