+/**
+ * UI_DEV_SETUP - Set device parameters for setup
+ *
+ * This ioctl sets parameters for the input device to be created.  It
+ * supersedes the old "struct uinput_user_dev" method, which wrote this data
+ * via write(). To actually set the absolute axes UI_ABS_SETUP should be
+ * used.
+ *
+ * The ioctl takes a "struct uinput_setup" object as argument. The fields of
+ * this object are as follows:
+ *              id: See the description of "struct input_id". This field is
+ *                  copied unchanged into the new device.
+ *            name: This is used unchanged as name for the new device.
+ *  ff_effects_max: This limits the maximum numbers of force-feedback effects.
+ *                  See below for a description of FF with uinput.
+ *
+ * This ioctl can be called multiple times and will overwrite previous values.
+ * If this ioctl fails with -EINVAL, it is recommended to use the old
+ * "uinput_user_dev" method via write() as a fallback, in case you run on an
+ * old kernel that does not support this ioctl.
+ *
+ * This ioctl may fail with -EINVAL if it is not supported or if you passed
+ * incorrect values, -ENOMEM if the kernel runs out of memory or -EFAULT if the
+ * passed uinput_setup object cannot be read/written.
+ * If this call fails, partial data may have already been applied to the
+ * internal device.

+ * UI_ABS_SETUP - Set absolute axis information for the device to setup
+ *
+ * This ioctl sets one absolute axis information for the input device to be
+ * created. It supersedes the old "struct uinput_user_dev" method, which wrote
+ * part of this data and the content of UI_DEV_SETUP via write().
+ *
+ * The ioctl takes a "struct uinput_abs_setup" object as argument. The fields
+ * of this object are as follows:
+ *            code: The corresponding input code associated with this axis
+ *                  (ABS_X, ABS_Y, etc...)
+ *         absinfo: See "struct input_absinfo" for a description of this field.
+ *                  This field is copied unchanged into the kernel for the
+ *                  specified axis. If the axis is not enabled via
