+ * Input Parameters:

+ * Returned Values:
+ * On success this function will return a non-NULL instance of struct
+ * usbhost_registry_s. NULL will be returned on failure. This function
+ * can only fail if (1) id is NULL, or (2) no USB host class is registered
+ * that matches the device class ID.
