 * Does no actual work.
 * Assumed to not be detectable by USB VID/PID,
 * and thus exposes an "auto-prober" to explicitly discover the device.
 *
 * See @ref writing-driver for additional information.
 *
 * This device has an implementation of @ref xrt_auto_prober to perform hardware
 * detection, as well as an implementation of @ref xrt_device for the actual device.
 *
 * If your device is or has USB HID that **can** be detected based on USB VID/PID,
 * you can skip the @ref xrt_auto_prober implementation, and instead implement a
 * "found" function that matches the signature expected by xrt_prober_entry::found.
 * See for example @ref hdk_found.
 * Alternately, you might create a builder or an instance implementation directly.
