This patchset enables hard wired hub device to use different bInterval from its descriptor when the hub has a combined device node.
When we know reducing autosuspend delay for built-in HIDs is better for power saving, we can reduce it to the optimal value. But if a parent hub has a long bInterval, mouse lags a lot from more frequent autosuspend. So this enables overriding bInterval for a hard wired hub device only when we know that reduces the power consumption.
