12.3.3.2 USB Device Configuration Example
The example descriptor structure in Figure 12-23 shows a device with three different
configurations. Refer to Chapter 9 of the USB Specification for information on the contents
of each descriptor.
This example is described in the configuration RAM sequence shown below. The device
descriptor begins at address MBAR + 0x1400. Each descriptor must immediately follow
the previous descriptor without any empty locations between them.
