TUSB8044A: Chaining Hub ICs

Part Number: TUSB8044A

Tool/software:

Is it possible to chain together a tree of the TUSB804xA chips in order to add additional port support? In our design we may need to support up to 9 USB ports. I also see that the 8044A pulls 672mA with 4 SS downstream devices connected, is my understanding of that correct? Is it using all that power to manage the data muxing?
