USB 2.0 device through a USB 1.1 hub

I need to detect if my USB 2.0 device is connected through a USB 1.1 hub so I can handle the device accordingly. The value of bcdUSB in the descriptor and device qualifier always shows me 200H(USB 2.0) with or without the hub. How do I get the actual USB speed for a device with a low/full speed hub in the middle?

Thanks.
