Hi Greg and mka,

Let's make it clear that we are talking about once this driver is approved into usb tree,
If we use different USB HUB which have VID/PID not defined in this driver,
We need to update this driver.

But if we defined VID/PID in device tree(for a specific board, manufacture should know VID/PID from HUB it used),
dynamic parsed by the driver, then we don't need to change this driver (increase VID/PID table).
